Cold War II alert: Rare earths could tilt the global balance of power

Gift this article
In retrospect, the symbolism of the moment was foreboding. On 15 May 2019, President Donald Trump signed an executive order banning US firms from doing business with Chinese telecommunications companies, including Huawei Technologies. Five days after that first broadside in a brewing trade-and-technology war, China's President Xi Jinping was photographed touring a factory producing rare-earth magnets.
In retrospect, the symbolism of the moment was foreboding. On 15 May 2019, President Donald Trump signed an executive order banning US firms from doing business with Chinese telecommunications companies, including Huawei Technologies. Five days after that first broadside in a brewing trade-and-technology war, China's President Xi Jinping was photographed touring a factory producing rare-earth magnets.
Such devices, his visit seemed to imply, could be a geopolitical weapon for China quite as potent as advanced semiconductors are for the US. Six years later, those battle lines are hardening.
In the first major US-China trade dispute of Trump's second term, Beijing was able to use its control of rare earths to force Washington to a deal struck in London recently. The magnets produced from them are essential for the lightweight powerful motors driving everything from automated car seats to guided missiles. After the US imposed its first round of tariffs in April, China started limiting export permits, causing US manufacturers to warn of imminent shutdowns.
Trump announced in a social media post last Wednesday that the trade deal had been finalized. But it had a worrying note of desperation. America has been caught napping.
Beijing's response to being frozen out of the microprocessor ecosystem was an all-out drive to bridge the technological gap. State-owned chip foundry SMIC has deployed $33.5 billion on capital expenditure and $4 billion on research and development (R&D) since the middle of 2019. Huawei spends $25 billion on R&D every year. Just 12 months ago, the government created a separate $47.5 billion semiconductor investment fund.
The US chip fortress still looks pretty impregnable, barring an unexpected DeepSeek moment. Although Huawei is reported to be developing a 3-nanometer chip to match the most advanced non-Chinese processors as soon as next year, the founder said its best designs still 'lag behind the US by a generation."

A lesson of asymmetric warfare is to exploit your enemy's weaknesses, rather than attempt to match their strengths. That's where rare earths come in.
A technological conflict is simply a disguised version of a real flesh-and-blood battle. As Chris Miller's 2022 book Chip War explains, the US advantage in semiconductors was a crucial factor in winning the Cold War. By making processing power incredibly lightweight and error-free, it enabled America to build a far more fearsome military machine. Cruise missiles guided by tiny onboard computers could destroy targets with pinpoint accuracy, rendering them more deadly than Soviet missiles that perennially veered off course.
Rare-earth magnets promise to replicate that processing-power revolution in mechanical power—making motors smaller, stronger, cheaper and more efficient. It's an innovative leap that allows us to move objects in undreamt-of ways. As with cruise missiles in the 1970s, this innovation promises to change the way future wars will be fought.
Blinded by culture wars over the energy transition, America is doing far too little to close this technological gap. Its military needs for rare-earth magnets, as we've written, have been pretty much met at minimal cost. Compared to the hundreds of billions that China is pouring into chips, the Pentagon has built a rare-earth supply chain since the start of 2020 with $439 million in grants and loans.
Worse is the way lithium-ion batteries are falling victim to politics. The looming repeal of Biden era clean-energy subsidies and the resultant collapse of the electric-vehicle supply chain may reduce the output capacity of US battery manufacturers in 2030 by about 75%. That would halt almost every plant not already under construction and ensure the country can only produce enough cells to power about a fifth of annual car sales. America will be left more dependent on China, both for auto batteries and the host of more crucial niche applications for lithium-ion technology.
In the golden age of semiconductors, the US instinctively knew that its strength lay in its determination to remain at the bleeding edge of innovation. When the might of the state forces technology to submit to ideology, though, the consequences can be disastrous. That's the road the US is on, however, in letting China take the lead in rare earths, solar panels, lithium-ion batteries and the other clean electrical technologies of the future.
Should American troops find themselves on some future battlefield without the minerals and batteries needed to match swarms of drones deployed against them, they'll rue the day Washington turned its back on the future. ©Bloomberg

Delhi must underline for Washington the grave dangers of Asim Munir's vision of Pakistan

In 2018, in his first term, US President Donald Trump had spelt out, in his typically blunt style, the sense that Rawalpindi and Islamabad had taken advantage of Washington: 'The United States has foolishly given Pakistan more than 33 billion dollars in aid over the last 15 years, and they have given us nothing but lies & deceit, thinking of our leaders as fools… they give safe haven to terrorists'. This week, he said: 'I love Pakistan'. It would be simplistic to view the unprecedented lunch meeting at the White House between Trump and General Asim Munir — the first time a military leader who is not head of state in Pakistan has been accorded the honour — as a major u-turn. Indeed, India-US ties have been steadily deepening over the last three decades, based on a convergence of economic and strategic interests and shared values, even as the US-Pakistan relationship has grown more volatile. That said, the current moment in international relations is one of flux and Delhi must tread carefully. The Pahalgam attack underscored the grave national security threat that Pakistan-sponsored terrorism continues to present for India. With Operation Sindoor, Delhi has made it clear to both Rawalpindi and the world that it will pierce the shield of 'proxies' and not give in to Pakistan's nuclear blackmail. India has raised the costs of terror in order to ensure that such attacks on its soil are not carried out with impunity. Communicating the new normal it has etched with Pakistan after Pahalgam to its friends abroad is Delhi's challenge. To be sure, Delhi cannot control who Trump chooses to engage, and for what reasons. Pakistan's geography — it shares a 900-km border with Iran — may make it an attractive tactical partner for the US in the current Israel-Iran war. There is speculation that Pakistan's rolling out the red carpet for the privately-owned US cryptocurrency firm, World Liberty Financial (WLF), may have helped ingratiate Munir to the White House — Donald Trump Jr has close ties with WLF. A White House spokesperson has claimed that Munir has proposed Trump for the Nobel Peace Prize for his self-proclaimed role — firmly denied by India — in the post Op Sindoor cessation of hostilities. For India, though, the question is less why the Munir-Trump meeting, and more about how to ensure that the red lines it has laid down are respected, including by the US. Just a fortnight before terrorists killed 26 people in Pahalgam after confirming their religion, Munir had reiterated some of the nastiest tropes of the two-nation theory. He called Kashmir Pakistan's 'jugular vein', and reduced the complex and layered identities of the Subcontinent's people to their religion. It is now for Delhi — diplomatically, through the appropriate channels — to remind Washington that Pakistan's Field Marshal is a fundamentalist with an army at his disposal. Delhi has done well so far in standing its ground and making it clear that it will not compromise on its national interest: Even if belatedly, it issued a clear denial of President Trump's claims about mediating the ceasefire. Now, it must underline for Washington the danger that Munir's vision of Pakistan poses for stability in the region and for global order — and why Delhi has drawn some hard red lines.

Iran-Israel conflict: Donald Trump warns Iran has ‘two weeks' to avoid US strikes

US President Donald Trump warned escalating tensions on Friday, giving Iran a "maximum" of two weeks to avoid potential American air strikes. His remarks come as Israel asserts it has already delayed Iran's presumed nuclear ambitions by at least two years. Trump also dismissed European diplomatic efforts, saying it would be "very hard" to ask Israel to halt its ongoing military actions, according to a report by AFP. A series of blasts were heard in Tehran on Friday as Israel kept up the massive wave of strikes it says is aimed at stopping Iran from developing nuclear weapons -- an ambition Tehran has denied. 'According to the assessment we hear, we already delayed for at least two or three years the possibility for them to have a nuclear bomb,' Israel's foreign minister Gideon Saar said in an interview published Saturday. Saar said Israel's week-long onslaught will continue. "We will do everything that we can do there in order to remove this threat," he told German newspaper Bild. As Trump mulls the prospect of joining the war on Israel's side, top diplomats from Britain, France and Germany met their Iranian counterpart Abbas Araghchi in Geneva and urged him to resume talks with the United States that had been derailed by Israel's attacks. French Foreign Minister Jean-Noel Barrot said "we invited the Iranian minister to consider negotiations with all sides, including the United States, without awaiting the cessation of strikes, which we also hope for." But Araghchi told NBC News after the meeting that "we're not prepared to negotiate with them (the United States) anymore, as long as the aggression continues." Trump was dismissive of European efforts, telling reporters, "Iran doesn't want to speak to Europe. They want to speak to us. Europe is not going to be able to help in this." Trump also said he's unlikely to ask Israel to stop its attacks to get Iran back to the table. "If somebody's winning, it's a little bit harder to do," he said. Any US involvement would likely feature powerful bunker-busting bombs that no other country possesses to destroy an underground uranium enrichment facility in Fordo. On the streets of Tehran, many shops were closed and normally busting markets largely abandoned on Friday. Since Israel launched its offensive on June 13, targeting nuclear and military sites but also hitting residential areas, Iran has responded with barrages which Israeli authorities say have killed at least 25 people. A hospital in the Israeli port of Haifa reported 19 injured, including one person in serious condition, after the latest Iranian salvo. More than 450 missiles have been fired at the country so far, along with about 400 drones, according to Israel's National Public Diplomacy Directorate. We will do everything that we can do there in order to remove this threat. Iran said on Sunday that Israeli strikes had killed at least 224 people, including military commanders, nuclear scientists and civilians. It has not updated the toll since.

Pakistan nominates Donald Trump for Nobel Peace Prize for ‘leadership' during India-Pakistan conflict

Pakistan has said in a post on social media platform X that U.S. President Donald Trump should get Nobel Peace Prize in 2026 'in recognition of his decisive diplomatic intervention and pivotal leadership during the recent India-Pakistan crisis'. Mr. Trump has repeatedly claimed credit for playing a substantial role in easing the conflict — despite Indian authorities disputing that. The nomination came after Mr. Trump was asked on Friday (June 20, 2025) about the Nobel and said he should be awarded it for a variety of reasons, including his work on India and Pakistan and arranging a treaty he said would be signed on Monday to end hostilities between the Democratic Republic of the Congo and Rwanda. 'I should have gotten it four or five times,' the President said. 'They won't give me a Nobel Peace Prize because they only give it to liberals.'
