Now we know why North Korea has never left Ukraine. Send missiles to Russia has made it a power

by

For a while nobody has heard more about North Korean troops In the Ukraine War. However, the nation has never left the conflict in Eastern Europe. In fact, now it has been known The scope of the collaboration between Moscow and Pyongyang. While North Korean missiles arrived in Russia, another package of measures and artillery has been transforming the military capacity of North Korea. A war and its missiles. I told yesterday The Guardian. A prepared report For the UN sanctions multilateral group of the UN, it has revealed that Russia is using North Korean armamentincluding ballistic missiles and heavy artillery, to intensify their attacks against Ukrainian cities and destroying critical civil infrastructure. According to this consisting team by 11 countries (Among them the United States, the United Kingdom, Japan and several EU nations), the Kim Jong-un regime has sent Moscow More than 20,000 containers With ammunition since September 2023, equivalent to some nine million projectiles of artillery and rockets. This massive arms supply, a VIOLATION OF RESOLUTIONS The UN Security Council has allowed Russia to hold and intensify its long -distance bombing campaign, especially in urban areas such as Kyiv and Zaporiyia. From Korea to Russia. The revelation arrives shortly after Kim and Putin signed An association treaty Comprehensive strategic in the summer of 2024. The same compromises both powers to Attend mutually If one of them is attacked. This pact formalizes a military alliance that already It had been brewing de facto through the systematic exchange of armament, technology and military personnel. The transfer of weapons It is not limited To projectiles: North Korea has supplied Russia Balistic missilesLong -range multiple launches, self -propelled cannons and other advanced ammunition, sent by sea, air and rail. Military Renaissance. For decades, North Korea dragged a chronicle inability to modernize His army. Isolated by international sanctions, devastated by natural disasters and impoverished by its own autarkic policy, Pyongyang maintained an oxidized military apparatus, with Soviet technology from the mid -twentieth century and insufficient resources to update it. However, and as explained this week The New York TimesRussian invasion to Ukraine has offered Kim Jong-un an unexpected opportunity: a military power needy ammunition, soldiers and conventional material. In exchange for supplying those millions of projectiles and thousands of troops, Kim has received from Moscow Fuel, food, technological assistance and a flow of weapons, components and knowledge that have completely transformed the North Korean military industry. Expanding arsenal. Thanks to this tacit exchange pact, North Korea has multiplied its capacity Armamentistic HE They have identified Modernized tanks with electronic war systems, attack drones led by artificial intelligence, advanced anti-aircraft systems, air-air missiles and naval destroyers equipped with supersonic cruise missiles. Ha also Test missiles Antiacera under the direct supervision of Kim, who has intensified his visits to ammunition factories and military facilities. He kamikaze drones trial With self -destruction capacity, directed by AI, it has been one of the most striking acquisitions, reducing the South Korea gap in the field of conventional weapons. These improvements reflect a Russian technological transfer that would have been unthinkable in the recent past. Troops, experience and diplomacy. Kim has not only exported ammunition. I remembered the Times that has also sent up to 15,000 soldiers North Koreans to the Russian Front, mainly in the Kursk region. Although Moscow initially hid his presence, in the end he recognized his participation as “significant”. For the North Korean regime, this deployment has an incalculable formative value: thousands of soldiers get real experience in combat, returning as veterans, something that not even the South Korean army can exhibit. According to analyststhis symbolic and strategic component full of pride to Kim and reinforces its internal and external image, providing it with greater margin of maneuver against key actors such as Trump or Jinping. If you want also, the result is a north Korea more assertivewith renewed military muscle and expanded negotiation capacity. North Korea nuclear submarine A pact without sanction. It is another of the legs that derive from the alliance. The Cooperation with Russia has allowed North Korea avoid effectively The sanctions of the UN Security Council, which explicitly prohibit the arms trade with the Kim regime. Plus: The Ukrainian conflict has facilitated A perfect route To overcome those restrictions. Moscow needs projectiles and soldiers, Pyongyang Technology and validation. The relationship, which began as A practical exchangehas been institutionalized with the signing of that alliance treaty that we commented. Since then, North Korea has intensified the construction of new destroyers Navales, has reactivated its program Nuclear submarines and has expanded its ammunition industry, multiplying by four its production of artillery projectiles. Naval ambitions. And of all, one of the most disturbing advances We commented recently: The presentation of Choe Hyon destroyerthe first of its class in decades, armed with cruise missiles similar to Russian 3m22 Zirconpotentially nuclear. To this is added the construction project of A nuclear submarinewhose only possibility is a qualitative leap in Pyongyang’s offensive capacity. Although many experts doubt that Moscow dares to share naval nuclear technology (especially a compact reactor for submarines), the fact that North Haya publicly shown The beginning of its construction suggests an unprecedented level of ambition. Its existence, even incomplete, already alters the strategic calculations of the United States and Japan in the Pacific. Errors and improvisations. No doubt, this meteoric advance is not exempt from errors: the recent shipwreck Of the second destroyer, which occurred shortly after his launch, caused Kim’s anger and the arrest of several officers. The incident reveals the pressure that the North Korean leader is exercising on his technical and military apparatus to accelerate development deadlines. Even so, with the support of Russia, these failures do not seem to stop the general rhythm of modernization. Kim has proposed to fulfill the ambitious arms program announced in 2021, and with the resources and knowledge acquired from Moscow, it is closer than ever to achieve it. Power rebalancing. Meanwhile, for Seoul, Tokyo and Washington, the North Korean military transformation … Read more

The world wants more and more matcha tea. The problem is that Japan is not being able to give it to him

by

For centuries Matcha tea It has been one of the most recognizable symbols of Japanese culture. Now is that and something else: a drink popularized by social networks and coveted in the international market to such an extent that, in Japan itself, there are stores that have been forced to limit sales by customer. The world is thirsty for Matcha. Increasingly. And that has triggered a deep imbalance in the market that will not be easy to correct in the short term. The big question is … why? Limited purchases. The market of Matchaa popular Japanese powder tea that is made with Técha leaves And it stands out for its bright green color, faces a complicated scenario: a considerable (and growing) decoupling between the supply and demand that has even led some suppliers to limit the amount of product they sell to their customers. Recently Nikkei Asia He spoke of online stores without stock or UJI and Kyoto stores in which only a single Matcha product per day is allowed to acquire. Nothing else. “Due to the strong and continuous increase in the demand for products in recent months, the current demand has already exceeded our production capacity,” Recognize The store Marukyu Koyamaen In a message posted on its website. “This translates into an extremely low inventory of all Matcha products at this time.” If the scenario were not complex in itself, it is added that there are producers who want to prevent their historical clients, such as temples, sanctuaries and places where the drink is used for ceremonial purposes, they are left short. A figure: 4,176 tons. The figures always help to better understand trends. And that of the Matcha boom is no exception. Although throughout the last decades the consumption of green tea and Matcha has been losing bellows in Japan, its success among foreign consumers has triggered the production of the ground TE. If in 2010 the country produced 1,471 tonsin 2023, according to the data of the Ministry of Japanese Agriculture (Maff), that volume had shot up to the 4,176 tons. Almost triple. The Japan Times Precise In addition, in the last five years, the sector has experienced a key change, orient more and more towards the international market: today more than half of the Japanese matcha ends up exporting. In general Nikkei Calculate That last year the flow of green tea exports reached 8,798 tons, ten times more than a couple of decades ago. Of that volume, powder tea, especially Matcha, represented more than half. The reflection in prices. The increase in demand has not long to move to prices, which draw an upward curve. After years down, the value of the tancha began to rebound after the pandemic and It has been consolidating little by little. In early May the Japanese newspaper The Asashi Shimbun revealed That, in the first auction of the year of green tea held at the Ja Zen-Noh Kyoto distribution center, the kilo reached an average of 8,235 yen, almost 67 dollars and 1.7 times more than a year ago. The value far exceeds the previous record, of 2016. Looking out of Japan. Interestingly, matcha fever comes after decades in which both the consumption of powdered tea and green tea in general has been losing strength In Japan’s households, which also explains that has decreased production. The causes of their renewed boom must be sought beyond, in an international demand that According to some analysts It moves to historical maximums. Only American buyers absorbed in 2024 44% of shipments International TEA powder. Second, quite a distance, Germany and Malaysia are. There are estimates that calculate that Matcha’s world market will be around 5,000 million of dollars in 2028, a more than considerable amount if one takes into account that in 2023 it stood at 2.8 billion. “In spite He recounts in Bloomberg K. Oanh ha. What is that boom? There is not a single factor that explains the growing world thirst for Matcha. When analyzing the phenomenon, analysts usually point out a key: the visibility it has reached in networks, both for its photogenic bright green hue and by the videos and comments that extol their health benefits, a message that seems to have penetrated above all After the pandemic. To that growing interest are added the changes in the consumption of the Matcha, which has ceased to be an exclusive drink of homemade ceremonies and meetings to join bottled drinks or even accompany chocolates and ice cream. And why not grow anymore? The tancha production has grown over the last years, expanding beyond the traditional areas of Japan. In addition, their farmers have seen how new competitors from China and South Korea arrived. So … why not that mismatch between supply and demand is not remedied? The key is in the limitations that the sector itself is found to expand its crops. The country has land, but plantations are not created overnight. It takes years In being lists and tancha leaves need to pass a storage and processing phase. Especially if farmers want to wear stone mills. The sector is not alien to the shortage of collectors and the lack of generational relief in a country that dealt with a serious birth crisis. Either to A record tourism flow that further tense demand. With that backdrop, farmers also face a fear that complicates the investments in the plantations: that the Matcha boom stays alone in that, a punctual fashion.

The US will revoke the visa of Chinese students to protect their AI industry. The risk is that he ends up wounding her death

by

China is by far the largest world graduate producer in Stem races (Science, Technology, Engineering and Mathematics), both in absolute and relative terms to the global total. The phenomenon is an exceptional magnitude, but there is a country that has just been slaughtered in their noses: United States. What happened. As they pointed out In The New York Times A few days ago, the US Secretary of State, Marco Rubio, advertisement that the Trump administration “would aggressively revoke” the visas of Chinese students. In these visa cancellations, those students with ties to the Chinese Communist Party (PCC) or those who study “critical fields” that did not define clearly but probably include that of AI will be included. Source: The New York Times. Impact. In 2024 in the United States, 20% of the visas granted to students went to young Chinese students. The measure is worrying for American universities, which depend on international students who pay the full cost – without scholarships – for their annual income. In addition, this decision affects both students who want to ask for a visa from now on and those who are already studying in the country. In total there are about 275,000 Chinese students in all types of university careers. Uncertainty. It is not clear what criteria will be followed to revoke these visas and not as quickly these measures will begin. Nor is it known if China will retaliate, although the number of US students in China is much less significant. In 2020 USA He already expelled to 1,000 Chinese students with ties with Chinese military schools. A massive practice. A report Published by the State Department and the NGO called the Institute of International Education indicated last year that China was the second country with the highest share of international students: only India “exports” more students. In the 2023-2024 COURSE, it received 1.1 million international students, of which 331,000 came from India (23% more than the previous year) and 277,000 from China (4% less than the previous year). Source: CSET. China is absolute power in Stem. If there is a “graduate” graduate producer “(science, technology, engineering and mathematics), that is China. Collected data By cset They reveal that in 2020 China led the number of graduates in these disciplines, with a total of 3.57 million students. Only India approaches with 2.55 million students, but for example in the US the figure is four times lower than in China: 820,000 graduates. Source: CSET. And the one that is most dedicated to these disciplines. Not only is it that China has the greatest number of Stem graduates in the world: it is that the percentage of students who choose these disciplines is also the largest in the world. 41% of students are launched to Stem Carreras. They are followed by Russia (37%), Germany (36%, Iran (33%) and India (30%). In the US, only 20%of students bet on scientific careers. Source: Macro Polo / Paulsen Institute. And that includes AI. In People’s Daily They pointed out A few days ago how approximately 50% of the main researchers of AI are trained in Chinese universities. The worrying thing for the US is not that: they depend a lot on them. A report of the Paulgo Institute of Chicago (USA) recently revealed that 38% of AI experts that develop their professional career in the US They have formed in Chinese universities. They are in fact more than those who have a strictly American origin (37%). China does not stop betting on Stem Education. Between 2012 and 2022 the budget spending of the Chinese government in education increased from 2.2 billion yuan (268,167 million euros) to 4.85 billion yuan (591,187 million euros), more than double. Several Chinese elite universities They have announced His intention to expand his curricula with the objective of prioritizing the strategic needs of the country, and here the AI ​​- who You start teaching in schools– It’s key. Imminent danger. This domain has a direct impact on the capacity of innovation, technological development and industrial competitiveness of China, but also of the countries that allow Chinese students to study and then work in international companies. Cut your wings to that talent is to cut them to innovation. The US will get just the opposite of what it intended. The analyst Alberto Romero explained How these measures are probably designed to protect national security – which Chinese students do not end up “spying” for China. “However, instead of helping the US to enhance their industry, what can happen is that they weaken it. Not only that: that revocation of visas can precisely help China meet their strategic objectives. Nvidia already notified with the hardware. The US opted to veto the export of its advanced chips from AI to China. The shot has come absolutely for the cylinder headand instead of preventing Chinese development and innovation, it has put a rocket. They do not seem to have learned the lesson, and revoke the visas to Chinese students can end up being an even bigger shot that comes out of an even bigger cylinder head.

China Ultima the preparations to connect the first commercial SMR reactor: Linglong-1 has completed the tests prior to fuel load and the network connection planned by 2026. Context. The International Atomic Energy Agency defines SMR as any reactor of less than 300 electric megawatts designed to occur in series and transport in the form of prefabricated modules until its location. Strictly applying that definition, there are only two facilities in the world with two SMR reactors each: Linglong-1. Now, the China National Nuclear Corporation (CNNC) prepares to connect to the network THE FIRST COMMERCIAL SMR. The Linglong-1 BC100 is a third generation pressure water reactor with a gross electrical power of 125 MW. The technology is 100% China intellectual. After completing cold tests, it will go to hot tests before connecting to the network in 2026 to generate up to 1,000 GWh per year, a production that would cover the average electrical demand for about 526,000 Chinese urban housingthe equivalent of a million people. If you replace similar coal centrals, you will save 880,000 tons of annuals. The advantages of SMR. Unlike traditional fission reactors, SMRs can be built in series in a centralized factory and transported in modules to the place where the central will be, which considerably lowers the costs. In addition, they include passive security systems systems, which allow insurance off without human intervention or external energy. These characteristics expand their deployment in islands, floating platforms or industrial complexes, such as mining or water desalination plants. China’s plan. Although China is the greatest world power in renewables, the deployment of minirreactors such as Linglong-1 is part of its 14th five-year plan to replace coal thermal plants. Linglong-1 aspires to supply clean energy in the free trade port of Hainan Island, acting as a showcase of Chinese SMR technologies export To the rest of the world.

The motorcycle fever of the 2,000 has brought to the absurd the price of the second hand. There are more expensive than 20 years ago

by

The price of second -hand cars It has been triggered for yearsand it is more than usual to find models that cost more today than new four or five years ago. It is a sector that is not alone. The second -hand motorcycle is more expensive than everand it is not necessary to point to especially exclusive editions. Some are selling at exorbitant prices, although with a certain trick. The lucky one. The Honda CBR1000RR-R Fireblade It is one of the icons of the sports motorcycle. Even more in its Repsol version, painted with the colors of the MotoGP team. It was an especially expensive motorcycle, that was sold for 11,799 dollarsabout 14,000 euros in Spain. Inflation has made its own and, 20 years later, this model is sold (the current CBR1000RR-R Fireblade) is sold for 25,500 euros, a price in the line of what the great Japanese manufacturers ask for for their supercar. The price. The revaluation of a unit in perfect condition of this Honda is shocking. One of them was sold in the London Motorcycle Show for 22,000 pounds, just over 26,000 euros to change. In Motorpasion Moto They echo a second unit, with an estimated price of between 10,000 and 15,000 pounds, waiting for a new owner. He never started. To achieve these figures that exceed the original price, some requirements must be met, some of them especially complex. These units are sold as an old concessionaire stock: they have never been started, conducted or enrolled. They are motorcycles with 20 years on their backs, but without use. It’s not just nostalgia. The fever for the 2,000 superbikes is real, and there is nothing more to see the revaluation of most models in Platforms such as Milanuncios. Motorcycles of 20 years ago with prices that touch the 10,000 euros if the unit is in excellent condition and with “few” kilometers. They are motorcycles specially oriented to circuit, they do not have electronics or the restrictions on emissions of current models, and are seen as authentic candies to enjoy driving in their purest state. Beyond the sports motorcycle. Finding second -hand units almost at the same price as new units is not something exclusive to the supercar motorcycle. According to Anesdor datathe average price of the general motorcycle has risen 30% in the last five years. And, to a higher displacement, greater increase in the price. Despite the slightest attraction in the occasion market, in Spain two occasion motorcycles are sold for each new motorcycle, with an annual growth trend that is around 5% year -on -year.

Intel plans to get fully into the market in which South Korean SK Hynix has become rich: memories for AI

by

The South Korean company SK Hynix leads the HBM memories market (High Bandwidth Memory) With a shocking authority. Your market share Broken 70%so that the remaining 30% are distributed by Samsung and the American memory manufacturer Micron Technology. These memoirs work side by side with the GPUs for artificial intelligence (AI). In fact, one of SK Hynix’s main clients, possibly the oldest, is Nvidia. According to the consultant Datam Intelligence The global market centers market for AI will grow annually 24.5%, so it will go from having a volume of 13,670 million dollars in 2024 to no less than 78,910 million in 2032. For designers and integrated circuit manufacturers compete in a market with this growth potential is crucial, hence several Chinese companies are planning to get into it. And for Intel represents a too juicy opportunity to let it escape. Intel and Softbank work together in a new type of memories for ia The manufacture of HBM memories is very complex. This is the reason why this market at the moment is distributed only to the three companies that I have mentioned in the first paragraph of this article. However, its great growth potential will surely cause other companies over the next few years. Intel is going to be one of them, although the interesting thing is that he will not compete alone or fight for the HBM chip market. Intel and Softbank have proposed to complete the development of a prototype and evaluate its viability from a technical point of view by 2027 This American company has founded a company specialized in the design and manufacture of memory chips from the Japanese investment group. His name Saimemory And he was born expressly to compete from you to you with SK Hynix, Samsung and Micron Technology. Your plan consists in developing a new type of High performance packed dram memory From some patents prepared by Intel and several Japanese research centers, among which is the University of Tokyo. Intel and Softbank have proposed to complete the development of a prototype and evaluate its viability from a technical point of view by 2027. In fact, they intend to manufacture on a large scale and market this dram memory stacked for ia before it ends this decade. The performance of HBM memories is very high, but, as I mentioned a few lines above, they are difficult to manufacture. In addition, they are expensive, they dissipate a lot of energy in the form of heat and consume a lot of electricity. Stacked dram memories, however, on paper will be easier to produce, more efficient, and also cheaper. If when they are really satisfied the expectations that have generated it is possible that They end up displacing HBM chips. In fact, Intel and Softbank are not at all the only companies that trust the potential of stacked dram memories; Samsung and Neo Semiconductor are also developing this type of chips, so before the Memoirs market expires this decade will be much more competitive than today.

The five years of updates are just the beginning

by

The European smartphone faces One of the greatest regulatory changes in its history. One that affects both the way they will have to start producing it and the future of their life cycle. As of June of this year, it will be more durable by law. But there is a B face in this regulatory change. Why the changes. The European Union has published The new mandatory energy labeling and design requirements as of June 20, 2025. The regulations are aimed at prolonging the useful life of this type of product, both in repair and software support and durability of batteries. The commission makes it clear: it wants less phones to be sold, and increase their shelf life through two key points. The ecological design. Manufacturers will have to guarantee minimums in the manufacture of their smartphones. Batteries must endure at least 800 load cycles and download retaining at least 80% of its original capacity. Will be obliged to make consumers available to consumers Criticism spare parts within 5 to 10 working days, for at least 7 years after the end of product sales in the EU. Access will be non -discriminatory for any professional repaire. Must ensure availability of Operating system updates For at least five years. The new label. In order for consumers to be clear about what each smartphone offers in durability, the Commercial labeling In the box of this product category. In itwill be valued from A to G (being the maximum score and g the minimum) how each of the following criteria meets. QR code that leads to the official website of the manufacturer with detailed information about the product. Commercial brand with which the device is identified. Specific name or identifier of the model in question. Energy Efficiency Scale, where A represents the best performance and G the worst. Letter indicating the concrete level of energy efficiency obtained by the device. Battery autonomy time by full load, expressed in hours and minutes. Evaluation of fall resistance, classified from the A (more resistant) to E (less resistant). Repair score, also based on a scale from A to E. Number of load cycles that the battery can support before reducing to 80 % of its initial capacity. Degree of protection against water, dust or immersion, according to the corresponding IP standard. Official number of the applicable regulation: Regulation (EU) 2023/1669. Tablets and exceptions. The changes posed by the EU will apply to all smartphones and tablets. No categories per range or price are established: the regulations will affect from the most economical mobile in the market to the best Flagship. Fixed wireless phones will also be included, which have a cargo station. There are two curious exceptions that are fought from the requirements: Folding mobiles with roller screen and the Computer Tablets (Tablets-PC, convertibles of more than 17.4 inches). Traditional folding are not saved from the new regulations, but those who have a screen that are enrolle. The small print. The changes raised by Europe, of a first glance, seem to play in favor of the consumer. The reality is that they are much more complex than the labeling hides. First, software support is an important expense for manufacturers. Although the current tonic is that it goes more, with cases such as Samsung, Google and manufacturers as honor offering between six and seven years of updatesthese update policies usually cover the most popular devices. The entrance ranges are the devices that offer the least margin to manufacturers, and prolong the support of a low -cost device that stopped being marketed years ago will involve extra costs. Extra costs that, depending on the commercial success of the device, They will be more or less assumable by the manufacturer himself. No one talked about versions. Europe will force manufacturers to update their devices for five years, but it is not detailed that it is strictly necessary to update the Android version. A two -year version support and three system updates is one of the most probable scenarios after the application is these new measures. It is also the most plausible solution to a problem related to the hardware of the input range devices: not all support five years of operating system versions maintaining decent performance.

The undercover operation of Ukraine has left an irreparable hole for Russia. Its nuclear deterrence has jumped through the air

by

If they had told us that a fleet of trucks disguised as mobile houses was going to enter Russia in a covert operation of a year and a half, and that after that time a swarm of more than 100 drones would attack with surgical precision several air bases of Moscow, we would not have believed it. However, and beyond A mission That seems more typical of a Hollywood film, the operation has meant a hole for Russia that can hardly be replaced in the short term. A letter clue In negotiations. Unprecedented. It We count yesterday. On June 1, 2025, Ukraine carried out the greatest operation with war drones to date, launching 117 drones against at least four Russian air bases in a coordinated attack that had as its direct objective the backbone of Russian strategic aviation: its long -range bombers. Until then, the Ukrainian attacks on these platforms had been sporadic and limited to a single location, but this blow, simultaneously executed against Belaya, Olenya, Dyagilevo and Ivanovo, says A radical change in the Ukrainian capacity to penetrate deeply in Russian airspace and degrade key strategic assets. Figures While there is still uncertainty about the exact number of destroyed or damaged aircraft, Ukraine claims to have impacted At least 41 aircraftwith 13 of them completely destroyed, including bombers Tu-22m3, TU-95msan early alert plane A-50 and possibly a TU-160 Blackjackthe most sophisticated bomber in Russia. An irreplaceable fleet. The importance of these bombers is not only in their conventional offensive capacity, but Its nuclear role within the Russian strategic triad. If the Ukraine figures are confirmed, the damages would be equivalent to a loss of the 10% of the force TU-95ms operational, for example, an alarming percentage considering that these aircraft have no immediate replacement. The TU-95ms, designed in the fifties and produced until the early nineties, It has been modernizingbut its value is more strategic than monetary. In the case of TU-22m3, another relic of the Cold War, its current use has been marked by devastating bombings with KH-22 missiles converted, causing Large number of deaths civilians in Ukraine. The loss of several of these airplanes greatly complicates their replacement. For its part, the TU-160the only one of these models still in production, represents a minimal fraction of the fleet and each unit costs more than 500 million dollars. Plus: Build new It has been for years and requires an industrial infrastructure diminished by sanctions. Your 22m3 Blow to nuclear deterrence. The Ukrainian attack, by Its scope and precisionnot only neutralizes short -term attack capacity, but also weakens Russia’s credibility as nuclear power. These bombers constitute the most flexible part of their Dysuasoria triadnot only for its role in conventional conflicts, but for its ability to launch nuclear missiles from remote distances. In addition, they also fulfill symbolic functions, patrolling the airspace of Europe, Asia and even approaching Alaska’s environment As a sample of force. The loss of aircraft in this sector undermines that projection. Moscow has repeatedly argued that attacks on its strategic abilities represent a red line, but so far it has not responded proportionally To attacks that have been growing in scope and intensity. This operation, however, marks An climb difficult to ignore. At 50u Structural vulnerability. The attack has also clearly exposed the persistent vulnerability of the Russian aviation on land. Although defensive measures implemented from previous attacks (such as aircraft dispersion, anti -explosive wallsreinforced shelters, models painted on tracks and wings tires To confuse drone guidance systems), the infrastructure has not achieved Protect airplanes whose large size even prevents them from protecting them completely. In fact, they were used junk aircraft Like lures, but none of that avoided the damage. The anti -aircraft defenses installed in the bases have been insufficient once again. The dispersion of bombers to remote places such as Olenya or Belaya intended to complicate Ukrainian attacks, but failed to avoid a huge scale and precision. Doctrinal change and a threat. Also We count widely yesterday. The Spiderweb Operation Not only demonstrated the technical capacity of Ukraine to infiltrate enemy territory with small and cheap drones, but also an emerging war doctrine focused on saturate and erode assets clue. This tactic not only damages expensive equipment with economic means, but it forces Russia to deploy even more Resources in static defensereduces its operational freedom and generates constant uncertainty. While Moscow launches nightly hundreds of drones against Ukraine, kyiv showed that he can strike back at unthinkable distances only one year ago. And it also does it with tools that evolve: the use of drones with improved countermeasures is expected, artificial intelligence To avoid The Jamming and the elimination of the human pilot in real time, which will further difficult to detect and neutralization. Putin and invulnerability. Bloomberg had Another leg that must be analyzed after the attack. Beyond the exact count of destroyed airplanes, the mission has shaken the Kremlin environment. The internal reaction itself has been alarm, anger and recognition of a scenario so far unthinkable: that nuclear assets can be legitimate and effective white from a country that No nuclear armament. Although the number of bombers needed to attack Ukraine is limited and Moscow could maintain its rhythm of envestidas, the underlying message seems clear: there is no territory Absolutely safe. This perception directly affects the Force projection that Putin has cultivated for two decades and erodes his rhetoric of strategic supremacy. The nuclear triad, touched. We said it at the beginning. Long -range aviation is the smallest component (and now, more damaged) Russian nuclear triadalso composed of intercontinental and strategic submarine ballistic missiles. Although bombers are frequently used in conventional missions, they are also part of the global deterrent gear. Its symbolic character as nuclear projection instruments add a layer of gravity to the attack. Even if its operating role within the nuclear arsenal is secondary to missiles or submarines, the perception that they can be neutralized from the interior of Russia represents that doctrinal change … Read more

We have just discovered a Mayan city of more than 2,800 years in Guatemala. And rethink the history of the region

by

The jungle of Peténnorth of Guatemala, he continues to surprise historians who are dedicated to exploring pre -Columbian history. There, near the border of Mexico, archaeologists have discovered a fascinating “Urban triangle” formed by three old cities that stand out for their architecture and heritage. Among all the most surprising is “the grandparents”, an important Mayan ceremonial center of More than 2,800 years of antiquity that takes its name of two pieces discovered by the experts: sculptures of an elderly couple who were probably used for rituals related to the cult of ancestors. The experts They recognize That the findings open the door to rethink what we know about ceremonies, society and pre -Hispanic politics in northern Guatemala. Beyond Uaxactun. For centuries the Mayan civilization extended in the south of what is today Mexico, Guatemala, Belize, El Salvador and Honduras, shaping a rich culture that dates back At least 2,000 ACreached its splendor during the 5th century of our era and declined in the post -classic stage, from X to XIII. During that wide period the Maya created great populations, as uaxactúna site located in the Petén region, in Guatemala. For some time, Guatemalan archaeologists have looked, however, beyond Uaxactún, towards the jungles of Petén, in search of old pre -Columbian cities. Hence, in 2009 they would boost the Uaxactún Archaeological Project (Paru), which explores a vast area of ​​around 1,200 square kilometers (km2) around the old Mayan city. Thanks to him and after more than a decade and a half of work, experts have cataloged about 176 deposits, from small archaeological vestiges to broader settlements. “An urban triangle”. That the researchers have found 176 sites does not mean that they have excavated them all. Over the last years they have observed three attention three, Mayan cities that have been studied thanks to the involvement of several Slovak institutions, including the Enoius University. Their conclusions have just been submitted and reveal Something amazing: an “Urban Triangle so far unknown” that lived its splendor in the Middle Preclassic (800-500 BC) and late and is formed by three cities that barely are far five kilometers each other. The discovery is interesting both for archaeological vestiges themselves and for the horizons they open. “The findings allow to rethink the understanding of the ceremonial and socio -political organization of the pre -Hispanic Petén,” They stand out from the Ministry of Culture and Sports of Guatemala. The three archaeological sites that have captured the attention of Guatemalan and Slovak experts and make up that new Mayan urban triangle are Petnal, Cambrayal and the grandparents, the most fascinating of all. A new archaeological jewel. Grandparents is a city dating from the Middle Preclassic (800-500 AC), reaches an extension of some 16 km2 and is located about 21 km northwest of Uxactún. In the opinion of the local authorities, it implies “one of the oldest and most important ceremonial centers of the preclassic in Petén.” In fact they expect light to contribute on the origins of Mayan civilization. His name is due to one of the most curious pieces found by archaeologists: human form sculptures that represent an ancestral couple and that experts relate to ancient worship rituals to ancestors. The initial dating places them towards 500 and 300 BC Architecture for stars. The sculptures however are only a small part of the archaeological treasure of the grandparents. In A statementthe Ministry of Culture highlights its “remarkable architectural planning”, with radial pyramids, triadic groups and sculpted monuments with an iconography of the region. “In addition to the sculptures, grandparents houses a type of architectural set known as group E, used as astronomical observatory,” They clarify. “The disposition of its buildings allows you to register with precision solstices and equinoxes.” Experts have known the Eaxactun Group E for years, but they believe that the one located in the grandparents could be even older. That without having the rest of the vestiges discovered. At the foot of the sculptures of the two ancestors, a human burial was located and not far from there remains of several felines, in addition to offerings of vessels, shells, arrow points and a trail from which archaeologists hope to obtain “valuable information” about the old Mayan settlement. Completing the triangle. The grandparents is the main course of the new findings presented by Guatemala, but not the only one. Another of the outstanding deposits is Petnal, a city that was equipped with a pyramid of 33 meters high decorated with preclassic murals. At their highest point, archaeologists have also discovered a well -preserved stay that still retains remains of painting on stucco with reddish, white and black tones, “another extraordinary discovery”, experts celebrate. Because of its characteristics and architecture, however they believe that, unlike grandparents, which probably acted as a “ceremonial center”, Petnal exercised political center. 57 meters of channels. The third city that completes the urban triangle of Petén is Cambrayal, equipped with a network of 57 meters long channels that part of a palace and extends through the facade. Interestingly, archaeologists believe that the channels, stuped, were not used to bring water to the rooms, but to evict waste, just like a primitive drainage system. Another piece discovered in Cambrayal by experts is a sculpture similar to others located on the southern coast. The Ministry of Culture of Guatemala Point out that the three cities share more than proximity and distribute throughout the petén. They all had a more or less similar story: the settlements remained inhabited during much of the preclassic, ended up abandoned and with the passage of the centuries they enjoyed a second golden age after being rediscovered, rebuilt and again populated, already during the stage called late classic.
