The US built the most powerful army in the world. Now there are those who point out its Achilles heel: cyberwar

Few countries have a military mix comparable to that of the United States: ground, naval, air and space forces, industrial capacity and the means to operate far from their borders. However, recent conflicts have made it clear that the superiority no longer depends solely of airplanes, ships or battle tanks. In Ukraine, drones have acquired a prominence that forces us to review tactics and defenses. Meanwhile, Cyberattacks have established themselves as another tool of confrontation. And that’s where some experts believe the American structure is starting to show problems. A commission assembled by the Center for Strategic and International Studies, in collaboration with the Cyberspace Solarium Commission 2.0s project, has tried to answer this question and its diagnosis is not very reassuring. In a recently published reportits authors maintain that the current design of US cyber forces is insufficient to deter, compete and combat in this domain. They do not claim that the Pentagon lacks specialists, units or operational capacity. The problem, according to the study, is deeper: no organization concentrates the responsibility of consistently recruiting, training and equipping the personnel needed by the United States Cyber ​​Command. It is no secret that measuring military power requires more than counting soldiers, ships or planes. The most visible data comes from SIPRI: in 2025, the United States remained by far the biggest military spender in the worldwith 954 billion dollars and 33% of the global total, compared to the 336 billion estimated for China. This data does not measure military power on its own, but it fits with other analyses, like those of GAO and Brookingswhich continue to describe the US as a dominant force due to its combination of capabilities, deployment, logistics and alliances. The domain for which no branch of the United States Armed Forces was designed There appears the anomaly that focuses the report. The United States has created military services with central responsibilities associated with the large traditional domains of combat, including the space branch since 2019. Cyberspace, on the other hand, continues without its own branch. The commission maintains that, for this reason, there is also no single authority responsible for creating the necessary forces to operate in that area. Responsibilities are distributed among different services, all involved in the mission, but none obliged to place it ahead of their traditional tasks. This dispersion translates, according to the report, into different approaches among the Department’s five military services to recruit, train and develop those who make up the cyber forces. Each one applies their own criteria access, career plans, educational systems and compensation models, which, according to the commission, produce unequal and inefficient results. Katherine Sutton, civilian cyber policy officer and senior cyber advisor at the Pentagon, acknowledged before the Senate Armed Services Committee on April 28, 2026 the “significant difficulties” in recruiting profiles with the appropriate skills, retaining the most experienced operators in the face of better-paid opportunities in the private sector and offering specialized training with sufficient agility. Now, the Pentagon has not stood still. The report acknowledges that it has attempted to correct part of the problem with CYBERCOM 2.0an initiative announced in 2025 to reinforce the role of Cyber ​​Command in talent, training and capacity development. But the commission considers that this type of reform does not resolve the underlying issue: the absence of a military branch dedicated to generating forces for cyberspace. In other words, it is not just discussing who commands the operations, but who stably builds the personnel, preparation and tools that those operations need. The United States Cyber ​​Command, known as USCYBERCOMhas the official mission of directing, synchronizing and coordinating operations in cyberspace to defend and promote national interests, according to its own institutional description. According to the commission, the problem is that in practice it also ends up carrying part of the “service-type” functions that it should provide. personnel, preparation and capabilities. The authors see there a design problem that is reminiscent of the model corrected by the Goldwater-Nichols Act of 1986which reorganized the Pentagon and better delineated the difference between building the force and employing it in operations. And what do they suggest? Well, the study works on the hypothesis of creating a military branch dedicated to cyberspace and develops how it should be organized if Washington were to make that decision. This Cyber ​​Force would have a defined mission: organize, train and equip the personnel in charge of offensive and defensive operations, while USCYBERCOM would retain the responsibility of employing them. The proposal does not seek to absorb all of the Pentagon’s technology or take charge of each of its computer networks. The other branches would continue to manage the systems linked to their own missions, but they would stop separately generating a capability that requires common criteria, careers and priorities. The paradox is difficult to ignore. The United States retains the most powerful military force in the world, but the report warns that has not yet developed a structure specifically designed to generate its capabilities in cyberspace. Erica Lonergan, lead author of the study and professor at Columbia University, and Mark Montgomery, commissioner of the report, retired rear admiral and head of cyber and technology at the FDD, They later transferred that conclusion to a forum in Defense News: If the digital environment has already become a war domain, it should have a branch ready to fight in it.

Iran’s Achilles heel is a tiny island located 25 km from its coast. The question is whether the US will dare to attack it

Until practically the day before yesterday Kharg island It was unknown to the vast majority of Europeans. Normal. To begin with, because it is thousands of kilometers from the heart of the EU, in the Persian Gulf, about 25 kilometers from the Iranian coast. It’s not particularly big either. It measures about eight kilometers long and 4.5 km wide. Despite all that, Kharg is perhaps the point that attracts the most attention. is hoarding (from Europe, but also the United States, China and Russia) in the convulsive geopolitical board with which March has started. The reason: the island is the key link of the Iranian oil sector. In a place in the gulf… Kharg Island is not exactly big. It measures 22 km2. What it does not have in surface area, however, it makes up for with its location. Located just 25 km from the Iranian continental coast and a few hundred kilometers from Strait of Hormuzis a strategic point for the global oil industry. The reason: that tiny island channels almost all of the crude oil exported by Iran. And those are big words if we take into account that, according to OPEC calculations, it is estimated that the Islamic Republic has confirmed reserves of 208.6 billion barrelsalmost the 12% of the total world. Is it that important? Yes. Iran enjoys a strategic position that (among other things) allows it to control the Strait of Hormuz, a strategic point for the commercialization of Middle East oil. In fact, it is estimated that almost a fifth of the world’s crude oil and gas pass through that narrow strip of a few tens of kilometers. However, not all are advantages for Tehran. Most of the Iranian coastline is bathed by shallow waters that complicate the movement of oil tankers. To operate with them, companies need to rely on Khrag, an island equipped with deeper docks and which since the 60s has had a powerful infrastructure built with the help of the firm. Amoco. Today it is the largest terminal exporter of the country. A percentage: 90%. Kharg’s role is best understood by dealing with various data. The main one is the volume of merchandise that it channels. It is estimated that almost 90% of Iranian oil exports pass through there, a bottleneck through which black gold flows before being shipped to the Strait of Hormuz. It may seem like an exorbitant percentage, but the island has the necessary infrastructure to charge seven million of barrels daily. Added to this are underwater pipelines connected to the country’s oil fields, storage tanks and housing for the complex’s operators. In the spotlight. Khrag has become the key link in the Iranian oil trade, but it also represents a kind of ‘Achilles heel’. Hitting the island means hitting the Iranian oil industry squarely. It’s nothing new. In the 80s Kharg has already suffered Iraqi bombings. The big question on March 9, 2026, with the US and Israel attacking the Islamic Republic is… Does Washington have any plan that involves controlling the island in one way or another? It is not a whimsical question. The Israeli army already has attacked several crude oil deposits and an oil transfer center located in Tehran and Alborz. The Axios weekend wakefulness In addition, Israel and the US have discussed sending special forces to Iran for various purposes: the main one would be to secure uranium reserves, but Kharg would also be in their sights. Ground operation? However, it is one thing to attack oil deposits and another to invade the island. For a start, remembers CNBCbecause it would require going one step further in the offensive in Iran and undertaking a ground operation. A hypothetical attack could also add more volatility and uncertainty to the industry at a time when a barrel of oil has risen to around $100. In the last hours the Brent even it touched 120. Cutting off the tap. The maneuver would also have advantages for Washington and Tel Aviv, especially when it comes to putting pressure on Tehran. Petras Katinas, an expert in energy and defense, recalls that if the United States controlled the island it could cut off “the oil livelihood” of the Iranian regime. “Looking ahead, confiscation would give the US leverage during negotiations, regardless of which regime is in power once the military operation ends,” insist. “It would deal a severe blow to the regime, since it would deprive it of a crucial source of income,” adds Tamas Varga, an analyst at PVM, who draws a parallel between what happened in Iran and the US intervention in Venezuela. in january. Why doesn’t the US act? For several reasons. We mentioned two (fundamental) before. Experts point out that taking Kharg would require a ground operation. And that, among other issues, could lead to even more instability in the region and the oil market at a delicate time. “Kharg could focus a multi-week attack campaign with Iranian drones and the island has mines and soldiers,” remember Marc Gustafson, who warns that an intervention of this type would not be without risks for the United States. He even mentions the possibility that, if the situation escalates, Iran will destroy its oil pipelines. One island, many drifts. If the US and Israel decide to comply with Kharg, Tehran could also see legitimacy to hit the oil infrastructure of other Gulf countries. That’s not counting, insists Michael Doran (from the Hudson Institute) in that it could complicate the post-war Iranian economy and the stability of any new government that takes the reins of Iran once the war ends.

We have found the Achilles heel of the most feared fungus in hospitals, and that already gives us hope

In the hospital environment there is a fungus that undoubtedly It is a real nightmare for modern healthcare systemssince it can put an entire hospital floor in check. We talk about the fungus Candida auris, which was first identified in 2009 and is undoubtedly a “superfungus” resistant to most common drugs and that it can spread quickly and be a silent epidemic that kills more and more human beings. Your weak point. Due to its aggressiveness, science has a clear objective: find your weak point to be able to develop a drug that allows us to destroy it. Now a group of researchers has published research in Communications Biology that changes the rules of the game: They have identified the exact genetic process that the fungus uses to survive inside the human body. And knowing its insides gives us options to destroy it. The iron problem. Like almost any living organism, this fungus needs iron to grow, replicate and cause damage. In the human body, iron is not “free” precisely as a defense system to prevent pathogens from using it against ourselves. Now science has seen that the fungus Candida auris It has a strategy to avoid this defense barrier that our body has. And the secret is in your genetics, specifically in some specific genes called XTCthat They literally act as ‘suction pumps’ which allows the fungus to capture iron even in the most hostile conditions. And this is the key. If iron is what feeds them, and we already know how they get the mineral from our own body… we already have the key to preventing them from consuming our own reserves. An unexpected ally. One of the biggest challenges in studying this fungus is that it has the ability to reproduce at high temperatures such as 37ºC. This makes it difficult to use traditional models to carry out studies, which until now were zebrafish, which want cold waters. To overcome this drawback, the research team used a rather innovative model: the killifish. A small fish that is capable of living in desert environments and tolerate temperatures of up to 37 °C, making it a perfect “living laboratory” to observe how the fungus behaves in real time within a vertebrate organism. Its importance. We must keep in mind that we are dealing with a pathogen that the WHO classifies as “critical priority”and that is why this research gives rise to creating drugs that attack the ‘suction’ system of fungi in order to defeat them. Plus, we already have something in our drug repository that we could use: iron chelators. An option that can ‘starve’ mushrooms, but has yet to be tried. In addition to this, the pathogens will be able to be identified much better, since there are strains of fungi that are much more aggressive because they capture a much greater amount of iron inside. The future. Although we have the focus about superbugs that can doom humanity, research must also focus on fungi that are developing resistance to specific treatments. In this way, finding a route that the fungus “cannot avoid” gives us, for the first time, a strategic advantage that we should not hesitate to use.
