What he has seen leads him to propose that retirees go back to work

Spain moves towards a demographic scenario that increasingly resembles that of Japan: fewer births, more longevity and a demographic structure that concentrates more and more weight at the top of the pyramid. This transformation is forcing Spain to reformulate the relationship between retirement and work with a new modality called reversible retirement, which aims to “recover” those who they have already retired to reintegrate them into the labor market and relieve pressure on the pension system. A country that ages rapidly. As they point out statistical dataat the beginning of 2024, Spain reached 48.6 million inhabitants and in 2025 we have already overcome the 49.1 million inhabitants. Of them, about 9.93 million were 65 years old or older (20.4% of the total), and about 2.95 million were over 80 years old (around 6.1%). This means that the demographic pyramid has reached cruising speed in the widening of its peak, while the base narrows at the bottom. decline in birth rate. In 2024, only 318,005 babies were born, which represents a historic low and 0.8% less than the previous year. as published The Country. With a life expectancy that already exceeds 84 years, the country faces a growth of number of pensioners and a progressive decline in the active population. The worst nightmare for a government. Japan: the canary in the mine. Japan has been facing a reality for years that now reaches Spain, so Spain can take advantage of its learnings to adapt its policies to the new demographic reality. The current situation in Japan is a snapshot of what awaits us in the near future. According to data of The Japan Times, In 2024, 29.4% of Japan’s population was 65 years old or older. The extension of working life is now almost a norm. In 2023 they worked 9.1 million Japanese over 65 years of age, chaining twenty years of consecutive increase. More than 33% of retirees between 70 and 74 years old were still active In 2022 and from 2021, companies are obliged to offer employment up to 70 years of age. This retention of the workforce beyond retirement age has allowed Japan to maintain its contributions, reduce pressure on pensions and mitigate the labor shortage experienced. Delaying retirement is not enough. Spain (as well as the rest of Europe) has been progressively increasing the legal retirement agea process that will culminate in 2027 with the ordinary age set at 67 years. However, the demographic data published by the Bank of Spain show that these measures, although necessary, are insufficient. The population that joins the labor market is inferior than the one leaving, and the constant drop in the birth rate implies that this trend will be accentuated in the coming years, so the balance between retirements and incorporations will continue to be insufficient, and the immigrant population He can’t even compensate for it. Reversible retirement: Spain is taking note. In July 2025, the Ministry of Inclusion and Social Security presented the proposal for a Royal Decree that transforms the current flexible retirement to make it more attractive for people who have already retired. The reversible retirement proposed by the Government allows those who have already retired, return to the labor market without losing their status as pensioners or penalizing their pension, but rather increasing it while become active again. Its objective is clear: encourage work beyond the legal retirement age to compensate lack of labor that the labor market suffers and, at the same time, alleviate the growing spending on pensions. Working improves pensions. The Ministry’s proposal eliminates previous restrictions and allows make pension compatible with work employed and adds the novelty of being able to do it also on one’s own, as long as the beneficiary had not been self-employed in the previous five years. For employed employment, a working day for retirees of between 40% and 80% of that of a full-time worker is allowed. The pension is reduced proportionally to the working day: if someone receives a pension of 1,200 euros and works half-time (4 hours), they would receive a pension of 600 euros plus the half-time salary. He big change It is in the 10% and 20% incentives for those who return to work after six months since they retired. Continuing with the previous example, the compatible pension of 600 euros would increase by 10% (60 additional euros), reaching 660 euros plus your salary. If the working day were 70%, the increase would be 20%. The reform seeks make reintegration attractive, eliminating the feeling of penalty that until now discouraged this modality.

Google has OpenAI cornered. Altman has reasons to go into crisis mode

Sam Altman has pressed the red button on OpenAI. After three years of being the startup that terrorized Google, it is now Pichai’s company that has the creator of ChatGPT on the ropes. Why is it important. OpenAI’s CEO sent an internal memo on Monday declaring “code red”: all resources are focused on improving ChatGPT. Projects like advertising in the free versionAI agents for health and purchasing or the deployment of the personal assistant Press are postponed. The company that forced Google to react is now the one that reacts. The backdrop. In 2022, Google panicked when ChatGPT changed our expectations about generative AI. Three years later, the roles have been reversed. Gemini 3, launched a few weeks ago, has surpassed OpenAI models in benchmarks key and in general it has arrived with a great reception. Marc Benioff, CEO of Salesforce, he said it bluntly a few days ago: “I’ve been using ChatGPT every day for three years. After two hours with Gemini 3, I won’t go back.” The figures. Google has gone from 450 million monthly active users on Gemini in July to 650 million in October. ChatGPT maintains leadership with more than 800 million weekly usersbut the speed at which Google is advancing is what has set off all the alarms. The difference in spending capacity is abysmal: Google brought in $102 billion in just the last quarterwith three quarters coming from advertising. OpenAI projects to reach 20 billion revenues this year, but will need 200 billion by 2030 to be profitable according to their own projections. Its infrastructure commitments add up 1.4 trillion dollars in the next eight years. The money trail. Google can afford to spend between $91 billion and $93 billion this year on AI infrastructure because it has a high-margin cash machine behind it. OpenAI, on the other hand, continues to rely on funding rounds while racking up record losses. Yes, but. OpenAI still retains advantages. Its 800 million weekly users represent a moat that can only be conquered person by person. ChatGPT is today synonymous with conversational AI in the same way that Google is with search. Changing the habits of hundreds of millions of users is much more difficult than convincing a few CEOs to switch chip suppliers. Between the lines. OpenAI’s refusal to monetize ChatGPT through advertising is increasingly inexplicable. Google dominated search precisely because it understood that an advertising model not only generates revenue: it improves the product. More users generate more feedbackmore purchasing signals allow for more personalized responses, and margins improve as scale grows. OpenAI has been avoiding this evidence for three years, but it has not stopped signing spending commitments exceeding one trillion. Unexpected twist. three years ago It was Google who declared code red in the face of the ChatGPT threat. The empire now counterattacks with an overwhelming structural advantage: control of distribution (Android, Chrome, Search, YouTube, Docs…), comfortable financial capacity and its own chips. OpenAI has users, but Google has the money, infrastructure and patience to fight a war of attrition. At stake. The question is whether OpenAI will survive as an independent company when its technological advantages evaporate and its business model continues to fail. Altman He usually says that he doesn’t like to think too much about the competition.. Those days are over. In Xataka | NVIDIA is the most valuable company in the world because it had no competition.

The terror of wars was always stepping on a mine. In Ukraine they carry scissors, because the panic is thinner: a spider web

In May we count that an unexpected weapon had begun to be added among the Ukrainian troops: scissors. Given the brutality of the conflict, a technology had sneaked in to evade electronic warfare and enter the enemy camp on both sides as he had not done before: destroying the lines, making attacks invisible and evading any attempt at interference. Now, the tangle of cables has intensified. A deadly web. In 2025, the Ukrainian front is no longer understood without a sky and ground crossed by thousands of drones and by kilometers of optical cable that transform the land into a physical and tactical tangle. What started as a technological revolution to compensate for human shortcomings has evolved into an industrialized war in which each innovation immediately generates a counter-innovation, and where Ukraine, which for years led the initiative, now faces a scenario in which Russia obtains a sustained advantage. Fiber optic drones (invulnerable to electronic shielding) have colonized trenches, roads and wooded areas, leaving visible and invisible networks that slow down every movement and that, in the middle of the night, they get confused with real traps. Narratives from units like the Ukrainian Rangers show a landscape in which advancing is as dangerous as retreating: cables hanging from trees, entrenched in mud, or accidentally attached to weapons and vehicles after each mission. There is no “safe zone.” The great transformation is not in territorial advances, but in the Russian ability to hit supply lines tens of km from the front. What yesterday was a rearguard today is a vulnerable gray zoneand what once required manned aviation is now accomplished by swarms of small, remotely guided vehicles. The explosions that convoys have reached on theoretically protected roads confirm that Moscow has given absolute priority to the war of attrition: attacking where it hurts most, preventing rotations, exhausting Ukrainian drone pilots and forcing brigades to walk dozens of kilometers on foot to avoid detection. This logistical pressure not only undermines military resistance, but also alters the political balance: a country that loses strategic depth also loses negotiating capacity. The Rubikon unit. It we have counted before. The appearance of Rubikon, the elite unit that reorganized Russian doctrine after the Ukrainian incursion into Kursk, marks a before and after. Recruiting the best pilots, integrating optical drones, FPV and “mother” platforms like the Molniya, they exported a lethal model to the Donbas: attack supply before infantry, eliminate enemy pilots before riflemen, destroy capabilities before positions. Its success lies less in technology than on the scale: Russia produces more, deploys more and lets China nurture its fiber optic industry without limits. In Pokrovsk (the crudest laboratory of this mutation) Ukrainian soldiers calculate that Russian drones surpass them in a ratio of 10 to 1. The city, turned into a puzzle of ruins where the front line changes every few hours, exemplifies how tactical air dominance has become the decisive factor in controlling the terrain. The Ukrainian crisis. Ukraine continues to cause severe damage in the final strip before the front, where traditional FPVs remain lethal. But the rest of the board has leaned against her: a shortage of optical cables, pilots forced to launch from ever greater distances, disrupted logistics chains and a military industry struggling to produce what Russia receives on an industrial scale. Some controls they insist in which the strategic error is to prioritize the destruction of Russian infantry instead of replicating the Rubikon model: hunt down the operators, saturate the logistics nodes and act in depth. However, any solution requires resources that Ukraine does not have and that its allies provide too slowly. Chinese fiber optics, the officers point outis tipping the balance with more weight than many Western diplomatic decisions. Between swarms and cables. The conclusion is disturbing: war no longer depends so much on territorial advances as on who controls the drone ecosystem, who has more operational pilotswho can saturate the most kilometers of enemy rear and who turns rival logistics into a prohibited zone. The front, turned into a spider web physically by wires and digitally webed by unmanned swarms, is being redefined at a speed that Ukraine struggles to match. If kyiv does not regain the technological initiative and achieve a steady supply of optical capabilities and long-range platforms, 2026 could be the first year in which Russia’s structural advantage in drones not only complicates Ukrainian offensives, but seriously limits its ability to sustain current defenses.

They are eight more than the Roig Arena in Valencia

On September 6, the Roig Arena, the stadium of the owner of Mercadona. It is a covered venue that will be the new home of Valencia Basket and also the new reference center for events and concerts. It has 20,000 seats, which makes it the covered venue with the largest capacity in Spain. Now Madrid has proposed taking the title away from them. Well, me more. Isabel Diaz Ayuso has presented a Self-Protection Plan with which the Movistar Arena will be able to increase its capacity, which is currently 17,543, to 20,008 spectators. The capacity of the Roig Arena is 20,000 seats, so Madrid would only overtake it by 8 seats. Until the inauguration of the Mercadona owner’s stadium, the largest covered venue in Spain was the Palau Sant Jordi with 18,500 seats. Why it is important. Concerts have become the favorite cultural event of the Spanish. According to SGAE datathe music business grew 77% this year, compared to declines in other cultural sectors such as cinema or television. The macro concerts that saturate ticket sales platforms and the exorbitant resales They are clear symptoms of this exacerbated culture of eventism. Ayuso’s plan is a declaration of intentions: to become the city with more, better and larger venues. TObasketball forum Ayuso’s plan also includes increasing the number of seats for sporting events from the current 13,000 seats to 15,000. During her visit to the venue, the president of the Community of Madrid stated that the change will be a boost for the celebration of Eurobasket in 2029 and that it could open the door to major sporting events, such as NBA games. However, in the case of basketball, the Movistar Arena will not be able to say that it is the venue with the largest capacity since the capacity of the Roig Arena is 15,600 seats. A short, but intense career. Since its inauguration on September 6, the Roig Arena has already received more than 1 million spectators, as noted in Lift-EMV. Of all of them, 600,000 have attended concerts, many of them with the sign ‘sold out’. Currently, there are already events scheduled until January 2027 and among the confirmed artists are Aitana, Amaia, Rod Stewart and Hans Zimmer. It is a fact: the Roig Arena has become one of the country’s leading music venues in record time. Madrid and the concerts. As we said, this plan underlines the importance of being the reference city for holding large concerts. A year ago Madrid believed it had its mega-concert cathedral at the Santiago Bernabeu. Pharaonic works were carried out to hide the grass and make an underground parking lot to accommodate all visitors. The problem came with sound problems, specifically poor soundproofing that has forced cancel concerts and move them to the Riyadh Air Metropolitan. While this is resolved, Madrid’s plan is to praise another of its reference venues.

direct aid for the purchase of electric cars with doubts to clear up

New year, new help. That is what the Government has presented with the Auto Plus Plana project that replaces the MOVES III Plan and the discomfort with which the consumer has encountered until now if he wanted to receive aid to buy an electric or plug-in hybrid car. The aid plan is part of the Spain Auto 2030 Plana broader and more ambitious project in which 300 million euros in aid are also contemplated to promote the installation of charging points and the confirmation that another 580 million euros will be available to launch industrial activities with the PERTE VEC designed to promote the production of vehicles and automotive-related components in our country. Regarding aid, the Government will make up to 400 million euros available to buyers starting next January 1, 2026. It will do so with direct intervention in them, so this time the budget will not go through the Autonomous Communities, one of the main criticisms that consumers and manufacturers have been making for some time. What can we expect from the new Auto Plus Plan With almost two years of delay, it seems that we finally have a date for the electric car buyer in Spain to receive a discount just at the time of formalizing the purchase of the vehicle. And it is that in February 2024the Government committed to having this new deal available in the next aid package to be approved. In December of that year, without reaching an agreement, the Executive confirmed that MOVES III Plan funds were expanded with the same conditions as until now. In January 2025 the scare came: the omnibus decree that contemplated aid fell and the funds with him. days later would be reactivated with a new vote in the Congress of Deputies. Now, the Government assures that from January 1, 2026buyers of an electric car will have the funds available at the time of purchase. That is, at the promotional price they can discount the help they should receive for buying an electric or plug-in hybrid car. The presentation has not mentioned what the discounts will be, which, until now, are the following: Electric cars and plug-in hybrids with 90 or more kilometers of autonomy: 4,500 euros guaranteed discount and an additional 2,500 euros if a car that is more than seven years old is scrapped. Plug-in hybrid cars with more than 30 and less than 90 kilometers of autonomy: 2,500 euros guaranteed discount and an additional 2,500 euros if a car that is more than seven years old is scrapped. It has also not been confirmed if these aids will be available for kilometer 0 and pre-owned cars, a modification that applies from 2023. Or the price ceiling to which these aids are applied, which, until now, has been 45,000 euros before the application of VAT. What is certain is that the funds will not be transferred to the Autonomous Communities, such as It had been happening with the successive MOVES Plan. In that case, each region received some funds, which caused a buyer to find that their Autonomous Community lacked them and in other cases there was availability. But, also, bureaucratic obstacles are eliminated that required documentation to be presented in each region in a different way (in some areas it was mandatory for the beneficiary to present it and in others it was allowed for the concessionaire to manage it). Likewise, waiting times to receive aid should be completely eliminated, in some cases reaching 18 months and which have taken manufacturers to advance aid to the buyer with credits of up to 7,000 euros at 0% that had to be returned as part of a last installment or an intermediate installment after 18 months.

Of course there is a museum with more than 900 rocks with the “face” of a human being. And of course it’s in Japan.

Japan is a country that seems taken from another dimension, where the craziest and strangest things (for us Westerners) can happen. The only place where we can find beautiful manhole coversmajestic snow sculptures, very strange contestsbizarre television seriesas well as restaurants with robots and a few other wonders that leave us with our mouths open. Rocks with human faces. Today’s protagonist is another gem that can only be in Japan, since it is the only museum in the world that exhibits more than 1,700 rocks, of which 900 have one characteristic in common: they all have the appearance of a human face, well, or at least a face with eyes and a mouth. It is about from the Chinsekikan museum. Where. In Chichibutwo hours northwest of Tokyo, we will find a very peculiar and unique place in the world, a museum with an impressive collection of rocks, which were collected for more than 50 years by its founder Shozo Hayama, and where we will find rocks that resemble everything from the face of Jesus to Elvis Presley. Its origin. The museum, which means ‘The Hall of Curious Rocks‘, is currently managed and curated by Yoshiko Hayama, the wife of the founder who died in 2010, and it is she who maintains the museum as her husband left it, since she wanted to pay tribute to him after dedicating much of her life to collecting ‘jinmenseki’ (rocks with a human face). All stones are like this, they occur as is in nature, and do not have any type of modification. The names. Mr. Hayama not only collected the rocks, but also named them according to their features, which is why we will find rocks named in honor of Boris Yeltsin and even fictional characters such as Donkey Kong, ET, Nemo, and many more. However, there are still several unnamed rocks, so occasionally Mrs. Hayama comes out to welcome visitors and takes the opportunity to ask opinions about possible names for the rocks that have not been named.

The DGT is “favoring massive fraud” with the V-16 beacons. We don’t say it, FACUA denounces it

Of favoring “massive fraud” and “very serious passivity.” This is how Rubén Sánchez, spokesperson for the consumer association FACUA, has defined the attitude taken by the DGT on the occasion of the arrival of the V-16 beacons, which will be mandatory from January 1, 2026 to replace the emergency triangles. The association defends that many drivers have bought beacons that are now useless. But, in addition, the press conference and the company’s statement also leave another door open: who and why are criticizing or defending the measure? “A massive fraud”. The words are not found in the statement issued by FACUA but he does pick them up Europa Press from the mouth of Rubén Sánchez, spokesperson for the association, who has accused the DGT of favoring a “massive fraud” with its “very serious passivity” in the face of V-16 beacons that are sold as “approved by the DGT” but in reality are not legal. At the press conference, Sánchez has been much harsher with Traffic than the association has published on its website, ensuring that “it is silent while a multitude of companies, manufacturers and sales platforms are making money at the expense” of consumers” and that the DGT is doing it “absolutely badly because it has allowed large-scale commercial fraud.” Because? Because some of the V-16 beacons that are sold as “approved by the DGT” are not valid, according to FACUA. The association assures that there are companies using this claim to sell their beacons but these do not meet the connectivity requirements and, therefore, an agent can fine the user if they use it in their car. How is it possible? There are two options in this case. The first is that, directly, the company that is selling these beacons is engaging in fraud. That is, you are knowingly selling a product using a claim that is false. Therefore, the best we can do if we find a particularly cheap beacon is review on the DGT website that we are facing a device that complies with all of the law. The other possibility is that the shopping centers have taken out of storage the beacons that began to be sold before their connection with DGT 3.0 was mandatory. At that time, it made perfect sense that the box stated that they were “approved by the DGT” but obviously they have been out of date. FACUA denounces the following: “The obligation to inform the consumer about “the essential characteristics of the good” and to provide him with “relevant, truthful and sufficient information” about it is also being violated, as established in articles 20.1.b and 60.1 of Royal Legislative Decree 1/2007, of November 16, which approves the consolidated text of the General Law for the Defense of Consumers and Users and other complementary laws” Tepidity. FACUA’s words contrast with those of other consumer associations. The most obvious case is that of OCU, who have been opposed on some occasions to the measures taken by the DGT, such as environmental labelingbut they have not been dissatisfied with the V-16 beacons. The consumer association has made publications specifying what requirements are necessary to have a V-16 beacon connected or dismantling hoaxes. Posts that come with discounts on subscriptions that have a V-16 beacon attached as an ol giftdirect sale of this product. Beacons, beacons everywhere. And the V-16 beacon has become the star product of Christmas. All the large surfaces are promoting this product with supposed discounts, large online shopping spaces such as AliExpress or Temu They take discounts on the product to their highest point. The companies telephone They deliver it with new contracts, Mail has it in its offices and driver associations such as RACE either RACC They also have theirs. It is the result of a process that has allowed certify the same product with very subtle differences and then sold under different names. The most flagrant and controversial case of recent days is that of Angel Gaitan. He influencer has repeatedly criticized the imposition of this new device but has not lost the opportunity to sell a beacon under your seal which, in reality, is the same as that approved by the inventors of the new device and those who received the first approval from the DGT to sell their beacons presuming complete legality.

“prehistoric fish with armored teeth does not exist, it cannot harm you.” The prehistoric fish with armored teeth:

“If you had been in Cleveland 360 million years ago, you would be swimming for your life,” said Rachael Funnel a few days ago and the truth is that he is absolutely right in the world. Not only because, at that time, the area in which the North American city is located was a shallow ocean, but because in those waters there was an exceptionally bizarre bug. Welcome to the world of Dunkleosteus terrelli. The fact that? In essence, a predator measuring more than four meters very different from any fish alive today. Although, to tell the truth, they were also different from any fish from 360 million years ago. And why are we talking about this now? Because it was just published a study in Anatomical Record in which the best preserved remains of the species (preserved for millions of years in layers of black shale) have been analyzed. And honestly, what they found is a little scary. They have been able to analyze in detail the bone plates that ‘armored’ the head and trunk of these fish. Furthermore, by analyzing muscle inserts and bone canals, they have unraveled the functional characteristics of the jaw, showing that, in short, we are facing a terrible predator. But ‘terrible’ in the literal sense. To begin with, because D. Terrelli It did not have teeth in the conventional sense: they had large blades of bone that worked with enormous blades that captured and tore apart everything they caught. To continue, because it is one of the first examples of the existence of a specific jaw muscle. The science of sea monsters. He Dunkleosteus terrelli is not news to us: “the last important work that examined in detail the mandibular anatomy of Dunkleosteus was published in 1932, when the anatomy of arthrodirans was still little known”, remembered Russell Engelmanprincipal investigator. For years (for decades!), we have been content to put bones back together correctly and that has prevented us from fully understanding what was happening. For example, not understanding the functionality of these creatures has prevented us from understanding many fundamental characteristics of sharks from an evolutionary point of view. In the end, behind all those bone plates, there was a huge amount of cartilage. That is to say, once again, the world of monsters hides many interesting things to understand natural history. Something that, although it may not seem like it, we still need. Image | Nell Conway In Xataka | We have found two prehistoric sea monsters in the largest cave in the world after 325 million years

The round of peace meetings in Ukraine has ended. Russia says it is “ready”, but for war with Europe

The last two rounds of contacts between the Kremlin and Trump’s envoys have confirmed that the peace process for Ukraine is technically alive, but politically blocked. Putin took advantage of the arrival of the emissaries to launch a verbal offensive: Accused Europe of torpedoing peace, suggested the EU “is on the side of war,” and said Russia does not want a continental conflict but that if Europe starts one, “we are ready right now.” A trapped peace process. For Moscow, the talks are “very useful” as they allow it probe the limits Washington and explore what it is willing to sacrifice in exchange for a stable ceasefire. For the United States, they are an opportunity to zoom in positions without openly acknowledging that the original plan favored Russia too much and was unacceptable to kyiv. Five hours of meeting in Moscow served to review successive versions of the US document, but not to generate a “compromise option”: Russia accepts some elements, rejects others with a “critical and even negative attitude” and, above all, keeps intact its objective of translating its military advances in territorial gains formalized on paper. Moscow red lines. At the center of the disagreement is the territorial question. Moscow insists Ukraine must resign to 20% of Donetsk which he still preserves, while boasting (not without response from kyiv) of having taken Pokrovska key logistical hub that had been in operation for more than a year trying to capture with a great cost in lives and material. This insistence is not only cartographic: is part of a maximization logicin which victories at the front are used as an argument to tighten political conditions. Added to this are other structural requirements: deep cuts in the Ukrainian armed forces, severe limits on Western military aid and a fit of Ukraine into the Russian sphere of influence that would empty its formal sovereignty of content. In this context, talking about “progress” is, in reality, talk about margins: Washington explores how far it can give in without kyiv perceiving it as a capitulation, while Russia calculates how far it can stretch its demands without completely breaking the diplomatic channel that is useful to buy time and legitimize its narrative. Parallel diplomacy and mixed signals. Witkoff and Kushner’s role adds a ambiguity layer to the process. They are not classic diplomats, but political emissaries who operate in a gray zone between official diplomacy and American domestic politics. His presence in Moscow, after meeting with Ukrainians in Florida and reviewing a 28 point plan which initially tilted the board towards Moscow, sends several signals at once: kyiv is shown that Washington “listens” to its objections and tweaks the document, Moscow is made clear that the White House is willing to continue negotiating concession frameworks, and Europe is reminded that the decisive conversation remains, above all, Washington-Moscow. The Trump statement Calling the war a “mess” that is difficult to resolve fits with that approach: rather than a closed strategy, the administration seems to seek an agreement that reduces the political and economic cost of the war for the United States, although the final balance is very delicate for Ukraine. Europe as a scapegoat. The Putin’s words on Europe reveal a perfectly calculated strategy: presenting European capitals as the real obstacle to peace, accusing them of “being on the side of the war” and of preventing Washington from closing an agreement. By saying that “Europe is preventing the US administration from achieving peace in Ukraine,” the Kremlin is trying several things at the same time: put pressure on the Europeans to lower their demands, feed the fatigue of war in Western societies and drive a wedge between the United States and its allies, suggesting that Washington would be more flexible if it were not bound by “European demands.” The added threat that Russia “does not intend to fight Europe, but is ready if Europe starts” has a double effect: it works as a military warning and, at the same time, as an internal message to reinforce the idea of ​​a besieged Russia that only defends itself. The risk of being isolated. For Ukraine, cross-play is especially dangerous. Zelenskiy insists on receiving security guarantees “livable” for the future, that is, mechanisms that prevent a new Russian attack once an agreement has been signed. HE frontally opposes to any formula that forces him to give up territory that he currently controls or to reduce his army to levels that leave him defenseless. But, at the same time, it knows that a part of the European capitals and the American political class are seeking, with increasing urgency, an outcome that freezes the war and stabilizes the front, even if that enshrines a status quo very unfavorable for Ukraine. Its margin consists of supporting in the European bloc tougher (those countries that see a bad agreement as a disastrous precedent for continental security) and to remember that any credible reconstruction involves using frozen russian assets and for a framework of Western guarantees that makes another Kremlin attack politically unaffordable. Putin’s calculation of strength. The threats “cutting off Ukraine from the sea completely” and intensifying attacks on ports and ships entering them fit into a broader strategy: combine slow but steady advances in the Donbas with the ability to strangle the Ukrainian economy and make the protection of its maritime corridors more expensive. Each city taken or partially controlled serves the Kremlin as proof that time is in its favor and that it can rise the price of peace at each plan review. Editorials from related media, as Komsomolskaya Pravdareinforce this idea by presenting the negotiations as a scenario in which Russia can afford to tighten its conditions as “more and more Ukrainian territory” passes into its hands. The implicit message is clear: if the current proposals already seem harsh, the next round could be worse for kyiv if the war continues. Uncertainty. The final result is a peace process that formally remains open, but that moves on a dangerous … Read more
