Trump Orders Immediate Resumption of U.S. Nuclear Weapons Testing Ahead of Summit with Xi

Move marks first American nuclear test directive in three decades; comes amid renewed nuclear competition with China and Russia.

Seoul, Oct 2025 : In a dramatic policy shift, U.S. President Donald Trump on Thursday ordered the immediate resumption of American nuclear weapons testing, just minutes before beginning a high-stakes meeting with Chinese President Xi Jinping in Busan, South Korea. The move marks the first such order in 33 years, signaling a sharp escalation in the global nuclear arms race.

Trump made the surprise announcement on his Truth Social platform while aboard the presidential helicopter Marine One, en route to meet Xi for trade negotiations. “Because of other countries’ testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis. That process will begin immediately,” Trump wrote.

“Russia is second, and China is a distant third, but will be even within five years,” he added, without offering further details.

The White House did not immediately clarify whether Trump’s order referred to nuclear-explosive testing—which has been banned under a global moratorium since the 1990s—or to flight testing of nuclear-capable missiles. The National Nuclear Security Administration, which manages the U.S. nuclear stockpile, has not conducted a full-scale nuclear test since 1992.

Trump declined to elaborate when questioned by reporters upon arriving for his meeting with Xi, leaving defense officials and allies scrambling to assess the implications of his declaration.

China’s Expanding Arsenal and Russia’s Show of Strength

The announcement comes amid mounting concerns in Washington over the rapid growth of China’s nuclear arsenal and Russia’s renewed nuclear brinkmanship. According to a recent assessment by the Center for Strategic and International Studies (CSIS), Beijing has more than doubled its stockpile of nuclear weapons—from around 300 in 2020 to an estimated 600 warheads in 2025—and is expected to exceed 1,000 warheads by 2030.

The CSIS report noted that a Victory Day military parade in Beijing in September showcased five new nuclear-capable systems, each capable of reaching the continental United States.

Trump’s order came just days after Russian President Vladimir Putin announced the successful test of a nuclear-powered cruise missile and a Poseidon nuclear torpedo, which analysts warn could devastate coastal cities by triggering massive radioactive tsunamis.

Speaking to reporters aboard Air Force One earlier this week, Trump criticized Putin’s missile tests, saying the Russian leader “should be ending the war in Ukraine instead of testing missiles.”

Putin, meanwhile, has continued to project military strength, overseeing nuclear launch drills on October 22 and the test of the Burevestnik cruise missile a day earlier—developments that have raised alarms across NATO.

Arms Control Tensions and Calls for Dialogue

Trump’s latest directive underscores a growing breakdown in global arms control frameworks, as both Moscow and Beijing pursue aggressive nuclear modernization programs.

In August, Trump had said he discussed nuclear arms control with Putin and wanted China to join future disarmament talks. Beijing rejected the idea, calling it “unreasonable and unrealistic,” given that its arsenal remains far smaller than those of the United States or Russia.

Trump first outlined his intention to pursue new nuclear arms limitation efforts in February, saying he wanted to initiate discussions with both Xi and Putin on “imposing mutual limits on nuclear arsenals.” However, Thursday’s announcement appears to mark a decisive turn away from diplomacy toward strategic signaling.

Analysts say a resumption of nuclear testing could carry serious geopolitical and environmental consequences. “A full-scale U.S. test would be interpreted in both Russia and China as a deliberate assertion of military dominance,” said Michael Carpenter, a former U.S. defense official. “It would effectively end the era of restraint that has kept nuclear testing in check for over three decades.”

A Return to the Nuclear Era

The United States last conducted a nuclear test in September 1992, under the George H. W. Bush administration. Such tests, which measure the performance of warheads and the reliability of aging stockpiles, provide valuable technical data but also carry immense symbolic weight.

The nuclear era began in July 1945 with the detonation of a 20-kiloton atomic bomb at Alamogordo, New Mexico, followed weeks later by the bombings of Hiroshima and Nagasaki, which ended World War II.

By invoking that legacy just before meeting Xi, Trump has reignited a global debate over nuclear deterrence and stability at a time when U.S.–China relations are already strained by trade disputes, security tensions, and competing visions of global order.

Whether Trump’s directive represents a symbolic warning or the beginning of a new nuclear testing campaign remains uncertain. But the timing—just hours before sitting down with Xi—sent a clear message: Washington intends to reassert its nuclear dominance in an increasingly unstable world.
