The US wants to turn Pax Silica, its AI supply chain alliance, into a wider economic security pact, to be endorsed in San Francisco on Sunday. EU countries have raised concerns, citing vague definitions, a terminology clash over superintelligence and risks to their regulatory autonomy.

The US is facing resistance from the EU over plans to expand its global AI initiative, Pax Silica, into a broader economic security framework aimed at protecting American technological leadership.

The latest draft of a US declaration, discussed by EU ambassadors on Wednesday and seen by Euronews, states that “economic security is fundamental to national security, and that no nation can be secure without securing its critical systems and technologies from those that would do it harm.”

Washington wants members of Pax Silica, a US-led coalition designed to secure supply chains for AI, semiconductors and critical minerals, to endorse the declaration at a ceremony in San Francisco on Sunday.

The EU joined the initiative in June despite reservations from France, after several member states had already signed up individually. But Washington's latest proposals have revived divisions within the bloc.

The declaration calls for a “common understanding” on protecting sensitive technologies and critical infrastructure by diversifying supply chains and coordinating responses to economic coercion.

It goes further, arguing that “durable economic security among trusted partners rests not on professions of friendship alone, but on the vigilant protection of the foundations on which our economies depend and on the active promotion of shared innovation and technological leadership.”

The concerns are rooted partly in Washington's previous attempts to restrict access to advanced AI technology.

In 2025, the Biden administration introduced export controls under its AI Diffusion Framework that would have limited access to the most advanced AI chips for several EU countries.

The Trump administration scrapped the measures shortly before they were due to take effect, but they would have created serious problems for the EU's single market, which is built on the free movement of goods.

The restrictions were also seen as a signal that Washington did not consider some EU countries sufficiently aligned with its approach to China.

The US has sought to curb China's growing technological capabilities by preventing Chinese companies from accessing the most advanced AI chips, largely designed by American firms such as Nvidia.

One sticking point in the latest declaration is its broad definition of sensitive technologies and critical infrastructure.

Some EU member states are demanding objective criteria, fearing that the current wording would give Washington considerable discretion to impose restrictions and pressure its allies to follow suit.

Another dispute centres on terminology. Trump is pushing the concept of superintelligence, while the European Commission has proposed an explanatory note clarifying that the EU understands the term to mean artificial intelligence.

For Brussels, this is more than a semantic distinction. It is a question of legal certainty, given that AI is already defined in key EU legislation, notably the Artificial Intelligence Act.

Washington has long opposed the AI Act and is now proposing a Pax Silica working group to explore innovation-friendly regulatory approaches.

On Wednesday, EU governments gave the Commission a mandate to represent the bloc and negotiate the content of the declaration with the US. But the Commission might not receive a mandate to sign it in time for the San Francisco ceremony.

“We affirm that the safeguarding of these sensitive technologies and critical infrastructure is a shared endeavour; that the security of each signatory is strengthened by the vigilance of all; and that we engage in this common cause as trusted partners,” the text concludes.

Mobilising against two existential threats

Data centre

First published at Walden Bello’s Facebook page.

I am sharing these thoughts a few days after Lula da Silva’s impressive electoral victory in Brazil. Democracy was under threat from fascism and the people came out in force to save it. What made the difference, according to many accounts, was the combination of street mobilisation and coordinated online protest to get people to vote.

Inspiration from Brazil

What is notable is how many people worldwide have drawn inspiration from Lula’s victory. In the days leading up to and after the elections, people the world over felt invested in Lula’s fate — whether they were in Africa, Asia, Europe or North America, they felt their future would be affected.

Hence the great sigh of relief and elation that was heard from Rio to Johannesburg to Jakarta. This feeling of global solidarity has revealed to many the vision of what we could accomplish if we translate that solidarity into a coordinated global movement to save democracy, save the climate, and save humanity from AI.

Ever since the world became aware of the climate crisis, pressure from civil society has been focused on getting governments to come up with an agreement to prevent the rise of global mean temperature by 1.5oC. That strategy has had some success, notably the Paris Agreement of 2015.

But the limits of that strategy have become evident a decade later: the voluntary climate reduction efforts nations have pledged will not prevent a rise of 2.7oC of global mean temperature by the end of the century, and meeting the target of $100 billion a year in climate finance for developing countries has had little success.

What we need is a global mass mobilisation that can move governments to take more decisive action to save the climate.

Lessons of the anti-globalisation struggle

If you think that is impossible, remember it was global mass action that stopped globalisation in its tracks and exposed the fact that it was not leading to prosperity but to great inequality, more poverty, and global economic crisis. If no one talks anymore about the so-called benefits of globalisation — the mantra we kept hearing in the late 1990s and the 2010s — it is because of global mass mobilisation.

Of course, the 1997 Asian Financial Crisis, the 2008 Global Financial Crisis and COVID-19 played a role, but global mass resistance was decisive. A landmark study led by Isabel Ortiz and her colleagues found that of the 2809 protests between 2006–20 they analysed, 1484 were related to neoliberal reform or structural adjustment; that is, issues

related to jobs, wages and/or labor conditions; the reform of public services; corporate influence, deregulation, and privatization; inequality; tax and fiscal justice; low living standards; agrarian/land reform; high fuel and energy prices; pension reform; housing; and high food prices.

In addition,

897 protests were for environmental and climate justice; against the IMF [International Monetary Fund], the World Bank, and the European Union/European Central Bank; against imperialism (United States, China); against free trade; in defense of the global commons; and against the G20.

These protests included transborder mobilisations against key instruments of globalisation: the World Bank, IMF, and the World Trade Organization. Protests against these multilateral institutions were among the most prominent of some 209 transborder protests in the period 2006–20.

The most decisive were the mass mobilisations that led to the collapse of the Third Ministerial Conference of the WTO in Seattle, in late November 1999, and the Fourth Ministerial Conference in Cancun, in 2003. The WTO was intended to be the key instrument in liberalising global trade and investment. With the collapse of the WTO ministerial conference in Cancun, the US and EU lost interest in the WTO as the main agency for globalisation. It also led to the widespread discrediting of the globalist project.

The point is mass protests made the difference in stopping the project of corporate-driven globalisation.

Data centres are great, juicy targets

We can do the same with the fight against climate change. Having demonstrations at COP climate summits is important, but it is better to have concrete targets that large numbers of people can unite and mobilise against at the local level.

AI data centres are great targets. Data centres consume huge amounts of water and energy that would otherwise be used for community needs. They also contribute tremendous amounts of carbon emissions that worsen the climate crisis.

US President Donald Trump is going all out for AI, partly because it needs huge amounts of energy that can only be provided by the fossil-fuel industry, one of his main backers. By targeting data centres, we would be hitting two existential threats to the planet and humanity: climate change and AI.

There are 12,250 to 12,660 data centres globally, of which 1136 to 1189 are hyperscale — indeed, city-size — facilities, serving the huge cloud and AI computing needs of Google, Microsoft, Amazon and other Silicon Valley giants. More are on the way.

They are being constructed in the Global North and South. In the US, the Yakama and other indigenous nations are resisting the construction of 240 data centres in the Columbia River area. But while much of the news coverage focuses on the resistance of communities in the Global North, opposition to data centres is also occurring in Andhra Pradesh and Maharashtra in India; Queretaro in Mexico, where Silicon Valley giants have built 32 water-intensive data centres on arid land; and Batam, Indonesia, where the community has protested against their water supply being consumed by data centres.

There have been cases of successful resistance. In Oton, Iloilo, in the Philippines, residents subjected the representative of a Norwegian firm seeking to build a data centre to such hostile questioning in a community meeting that the proposed project was cancelled.

Pax Silica: A value chain whose links are great targets

The opportunities for protest will be expanded by the implementation of Pax Silica. This US initiative, which includes 26 countries, is meant to create a value chain from the mining of minerals such as lithium through to the running of data centres. All sectors of the value chain are carbon and water intensive. Therefore, all major points along the value chain could potentially be sites of protest. 

In the Asia Pacific, Japan, India, South Korea, the Philippines and Singapore have already signed on to Pax Silica. In the Philippines, the Marcos Jr government is devoting more than 1600 hectares — the size of a small city — to hosting an AI complex, even though foreign corporations have yet to make investment commitments. Even before Pax Silica has taken off, it has already united so many oppositional forces in a way no issue has been able to in the past few decades.

AI value chain links, from mining to data centres, provide the potential of uniting people beyond political differences in other countries. Data centres are so unpopular that they have become one of the hottest issues in the US midterms, with pro-tech politicians busy backtracking from their previous positions.

Targeting data centres need not be the only strategy in building a mass movement against climate change that forces corporations and governments to take decisive action. There can be various complementary strategies based on one conviction: unless people come out in force, as they did in Brazil, the factors pushing two existential risks to humanity — climate change and AI — will not be stopped.

This is a revised version of Bello’s presentation at the Conference on Planetary Well Being from the Ground Up, Chulalongkorn University, Bangkok, October 31, 2026.


The Greatest Existential Risk of the Early 21st Century

To dominate supply chains, the Trump administration is weaponizing the global AI race. Instead of learning from the lessons of postwar atomic regulation, the administration is reversing them, thereby paving the way for catastrophic risks.

by | Nov 5, 2026 | 

Anthropic’s IPO filing on Monday set the stage for the Claude creator to pursue possibly largest initial stock offering in history. According to CNBC, investors are measuring the 5-year-old company’s potential market cap in the trillions, putting it in a category with the world’s most valuable companies, even as the stock market is showing signs of jitters on the AI trade.

Anthropic devoted 94 pages of its 400-page securities registration statement to the “risk factors” section. “If misused, replicated, weaponized, or operated with a high degree of autonomy,” Anthropic acknowledged, “it could pose catastrophic or existential risks to humanity.”

On September 29, President Trump convened the CEOs of the leading U.S. AI companies and announced a voluntary “Joint Commitment on Frontier Responsibilities.” The agreement calls on frontier-AI developers to establish robust internal controls, use independent external auditors, and create board-level committees to review safety assessments. But since it is not legally enforceable, it is neither “morally binding” nor a “constitution” for AI safety.

The AI giants being asked to police AI admit that increasingly autonomous systems can behave in ways their creators did not anticipate. Yet, they are promoting the unpredictable products within the US military-industrial complex. The net effect? A historical acceleration of existential risks. 

Weaponizing U.S. technological primacy      

Trump has repeatedly framed AI as a competition between the United States and China, saying there will be “a winner and a loser.” He has rejected cooperation with Beijing because he believes the US is already leading.

But the administration is not just pursuing laissez-faire economics. It is constructing an AI-national-security-industrial complex.

In January, war secretary Pete Hegseth issued Pentagon’s milestone AI memorandum, which laid out a plan with a drastic focus on acceleration, not deceleration. “Speed wins,” Hegseth wrote.

In spring, according to the CNN, a U.S. Special Operations Command analyst used a large language model that almost misled the U.S. into instigating a war with China.

And yet, the June 2026 national-security memorandum directed the U.S. national-security establishment to obtain the most advanced AI systems, rapidly integrate commercial and open-source models, build high-security computing infrastructure and establish a strategic reserve of AI expertise.

The objective is a “decisive and enduring AI advantage” over adversaries.

This fosters an odd hybrid of market freedom, enormous public infrastructure, military integration and geopolitical protectionism, without legally enforceable safety regulation.

AI ecosystem is already transnational            

In view of the economic rationale, frontier AI exhibits enormous potential first-mover advantages. So, Washington is unwilling to impose rules that might slow U.S. companies while China continues developing its own ecosystem – even at the risk of accelerating catastrophic risks.

The problem is that AI is already transnational.

American companies depend upon global supply chains; advanced chips involve Taiwan, South Korea, Japan and Europe. Models circulate globally. Open-source weights cross borders instantly. Researchers move internationally. Cyber vulnerabilities are inherently transnational. And AI systems increasingly interact with infrastructure belonging to other countries.

International community cannot accept an exclusively U.S.-controlled AI order.

China is simultaneously pursuing rapid AI deployment and a substantially more state-directed safety regime, including mandatory safety assessments and emerging standards for autonomous agents. Its 2025 Global AI Governance Action Plan explicitly calls for international cooperation, safety, controllability and inclusive participation.

Europe is moving in a different direction. The EU AI Act imposes obligations on general-purpose models and substantially stronger requirements on models classified as presenting systemic risk.

Trying to make the U.S. the sole gatekeeper risks converting an already competitive technological system into a fragmented geopolitical system. Instead, what is needed is international multilateral cooperation.

The military-civilian debate over atomic regulation

Following the success of the Manhattan Project, a fierce debate erupted over the military and civilian architects on who should control the newly unlocked power of the atom. General Leslie Groves, who directed the Manhattan Project, championed military retention, while J. Robert Oppenheimer, director of the Manhattan Project’s Los Alamos Laboratory, and a coalition of scientists fiercely advocated for civilian governance.

Groves’s stated priority was national security. He and the War Department viewed atomic energy primarily as a supreme weapon of war. They believed that maintaining strict military secrecy and keeping custody of the weapons stockpile was essential to deter foreign adversaries, especially, during the emerging Cold War.

By contrast, Oppenheimer insisted on civilian leadership. As scientists, Oppenheimer and his peers knew that the atom held significant dual-use potential. Atomic energy was not just a bomb. It had immense civilian potential for medical research, electric power, and peaceful scientific progress. Military control would choke off open scientific inquiry. Furthermore, they hoped to prevent the transformation of the United States into a permanent garrison state.

Finally, the scientists believed in international cooperation. A military-run agency would signal aggressive intent to the rest of the world, making international arms control and treaties structurally impossible.

Atomic and AI Regulation: existential lessons and risks  

The atomic debate shares striking structural commonalities with AI regulation, though the modern landscape features unique complications.

DimensionAtomic Energy (1946)Artificial Intelligence (Present)
Primary ActorState-funded military project (Manhattan Project)Private commercial tech corporations (e.g., Anthropic, Google)
Nature of ThreatHardware bottleneck: Limited by access to physical uranium/ plutonium.Software proliferation: Scalable, dual-use code that is easily copied and distributed.
Regulated DomainHigh-energy physics, centralized weapon facilities.All-encompassing digital infrastructure (societal, corporate, military).

 

Like nuclear power, AI is dual-use technology. While it powers autonomous weapons, it also drives medical breakthroughs, consumer software, and economic growth. Restricting AI entirely to a national security framework risk strangling open innovation and commercial progress. But unlike the 1940s, the state does not own the technology; private corporations do.

Hence, the effort of the Trump administration and Defense Secretary Pete Hegseth to push for military/national security overview. The two seek to filter AI governance through a hyper-accelerated national security lens, as evidenced by the establishment of the four-star Autonomous Warfare Command (AUTOWARCOM). The logic centers on three tenets.

First, the “wartime speed” race against China: The administration believes that traditional, civilian-led bureaucratic regulatory bodies are sluggish, risk-averse, and counterproductive. In their view, the U.S. is locked in an existential technological arms race with foreign adversaries, mainly China.

Second, hostility toward private sector “guardrails”: When AI firms like Anthropic refused to strip out safety guardrails that prevent their models (such as Claude) from being integrated into fully autonomous offensive drones or surveillance tools, Hegseth designated them a “supply chain risk” and blacklisted them. The White House views civilian ethical constraints as a vulnerability that hampers national security.

Finally, bypassing domestic regulatory agendas: By framing AI primarily as an asset of national survival and weaponization, the administration shifts the center of gravity away from civilian federal agencies (like the FTC or DOJ) and places it into the hands of military and intelligence entities like the newly formed Technology Support Office (TSO). This allows the Pentagon to retain unrestricted, unhindered use of the computing architectures.

How 2026 is falling behind 1946                       

In the aftermath of Hiroshima and Nagasaki, civilian leadership won the battle on the control the of the atom. The Atomic Energy Act of 1946 (McMahon Act) established the U.S. Atomic Energy Commission (AEC) under strict civilian authority, dealing a heavy blow to the Pentagon’s initial plans.

There were three reasons for the civilian triumph. Oppenheimer and the newly formed Federation of Atomic Scientists engaged in a smart, coordinated public relations and congressional lobbying campaign, framing atomic energy as a turning point for humanity, not just a military asset. Second, they were supported by congressional skepticism of military monopoly. Finally, even President Harry S. Truman supported civilian control.

Unfortunately, AI regulation is unlikely to benefit for similar tailwinds. Today, the leading AI scientists operate in the corporate sector, not in the public realm. Second, decades of forever wars have dramatically transformed the Capitol Hill, due to the increasing share of congressional members with military, intelligence and security background. To win and retain their seats, most rely on financial contributions by the military-industrial complex and related industries.

To make things even more challenging, the Trump administration, blinded by faded fantasies of U.S. unipolar primacy in an increasingly multipolar world, rejects the idea of civilian control.

And so, the scene is set for catastrophic risks – in the name of national security.

Tiny melt traces shed light on the Colorado Plateau's explosive past



Tiny traces of melted rock have revealed new clues about the Colorado Plateau's explosive past. By studying these traces, researchers have gained new insights into what occurred deep beneath the Earth's surface millions of years ago

Deep beneath the Earth's surface, some minerals hold clues to processes that happened millions of years ago. One such mineral is lawsonite, which forms under high pressure and relatively low temperatures. What makes it significant is its ability to store water within its crystal structure and carry it deep into the Earth as tectonic plates move beneath one another. When exposed to high temperatures, lawsonite can break down and release this water, potentially causing surrounding rocks to partially melt. Understanding this process can help scientists learn more about how rocks change underground and how magma forms.

Now, researchers in Japan and Germany have found evidence of this process in an ancient rock from the Colorado Plateau. Microscopic traces preserved in the rock reveal a previously overlooked episode in its journey from deep underground to the surface.

"What makes this discovery particularly interesting is that we found what we believe to be the first evidence of lawsonite releasing water and causing partial melting in a natural rock," says Professor Tatsuki Tsujimori of Tohoku University's Graduate School of Science. "These tiny traces of melting can help us piece together what happened deep beneath the Colorado Plateau millions of years ago."

Around 28 million years ago, the Farallon Plate, an ancient tectonic plate sinking beneath North America, released water into the surrounding mantle. This water spread through the rocks deep underground in an event known as the Great Hydration. Scientists believe this event contributed to the region's uplift and powerful explosions that brought rocks from deep underground to the surface.

However, one question remained unanswered: how were these rocks transported from deep underground to the surface?

To investigate this, the researchers studied an ancient eclogite xenolith, a fragment of rock that formed under extremely high pressure deep inside the Earth.

By examining the rock under high-resolution microscopes, the researchers discovered unusual changes in omphacite, one of the main minerals in eclogite, along with tiny pockets of silica-rich glass, suggesting that the rock was heated to temperatures above 800°C, causing parts of it to melt.

Although the original lawsonite was no longer present, it had left behind distinctive mineral structures and traces of melted material, suggesting that it had broken down and released water during heating deep beneath the Colorado Plateau.

The researchers also found evidence that this heating occurred relatively quickly. Their calculations suggest that it could have lasted less than 10 years if the rock came into direct contact with hot magma at around 1100°C.

Together, these findings suggest that the rock reached the surface in two stages. First, hot magma carried it upward from deep inside the Earth, heating it along the way. The rock then cooled at a depth of less than about 60 kilometers before a later explosive event associated with volcanic activity brought it to the surface.

This provides new insights into how water, magma, and rocks interact deep inside the Earth, helping scientists better understand the geological history of the Colorado Plateau.

The study was published in Journal of Petrology and selected as an Editor's Choice article. The research was conducted by scientists from Tohoku University, JAMSTEC, the University of Bayreuth, and Ehime University.

From intense UV radiation and extreme temperatures to wind gusts and lightning strikes, wind turbine blades are engineered to withstand some of the harshest conditions. But that durability becomes a problem at the end of their lives, because the blades are also difficult to break down and recycle. 

Reporting November 6 in the Cell Press journal Chem Circularity, researchers found a way to give discarded wind turbine blades a second life. By subjecting the blades to a brief burst of intense heat, they transformed the waste into silicon carbide and graphene, two valuable materials for manufacturing. The method could cut up to 83%–92% greenhouse gas emissions compared to conventional recycling strategies while also turning a profit. 

“Wind turbines typically have a service life of around 20 years,” says senior author and chemical and environmental engineer Bing Deng of Tsinghua University, China. “As aging turbines are decommissioned, especially in China, where wind power has expanded rapidly, much of the waste has ended up in landfills. It’s a waste of resources.” 

The team’s method takes advantage of the blades’ own chemical makeup. Wind turbine blades are usually made from silica-containing fiberglass and carbon-rich polymer resin. Using a technique called flash Joule heating, the researchers heated the waste to about 2000°C (3632°F) in seconds. At this temperature, carbon can react with silica to form silicon carbide, a hard, heat-resistant material. Meanwhile, carbon can also reorganize into graphene, a material known for its strength and ability to conduct heat and electricity.  

The researchers found that adding the broken-down blades to other materials made the materials more useful in several contexts, including for new wind turbines. Just 0.3% by weight of the recovered materials made resin stiffer and stronger and improved its resistance to deformation by 27% under tension and 9% when bent. At 0.1% concentration by weight, the materials increased the resin’s thermal diffusivity by 41%, allowing heat to spread through more quickly. 

“The mixture of silicon carbide and graphene can be incorporated back into resins for new wind turbine blades, improving their mechanical and thermal properties,” says Deng. 

Beyond creating valuable new materials, the process could offer a cleaner and more economical alternative to conventional recycling techniques such as pyrolysis, which uses heat to break down polymers into oil and gas, and chemical dissolution, which uses solvents to separate resin from glass fibers. The new method could cut greenhouse gas emissions by about 83% and 92% compared with pyrolysis and chemical dissolution, respectively. 

“With conventional recycling methods, you have to spend money to process the waste. But our method could actually turn a profit of about $80 per ton because the recovered silicon carbide and graphene are valuable,” says lead author and environmental engineer Hao Bi of Tsinghua University. “By comparison, pyrolysis costs about $460 per ton, while chemical dissolution costs about $1,800 per ton.” 

The team is working on ways to scale up their process and is hoping to collaborate with partners in the industry. Their method could also be adapted to process other durable materials used in aerospace, automotive manufacturing, electronics packaging, and construction.  

“This is more than recycling. It’s upcycling,” says Deng. “We’re turning something that has little value into something that’s worth much more.”
