Trump stuns with call to resume nuclear tests — why now, and what it could mean

President Trump announced the U.S. would revive nuclear weapons testing, instructing the Pentagon to begin immediately on an "equal basis" with Russia and China, despite the U.S. moratorium since 1992 and uncertainty regarding current adversary testing. Experts suggest this could involve low-yield nuclear explosive tests or nuclear-powered weapon systems, viewing it as a strategic move to counter perceived adversary actions, potentially ahead of arms control talks. The announcement has drawn mixed reactions, with some supporting it as a necessary response to geopolitical shifts, while others warn it risks destabilizing global nonproliferation efforts.

Analysis

President Trump has announced a directive to revive U.S. nuclear weapons testing, instructing the Pentagon to begin immediately, citing alleged testing by Russia and China. This move is significant given the U.S. has maintained a moratorium since 1992, and the actual extent of current adversary testing remains ambiguous, with experts suggesting the directive could target low-yield nuclear explosive tests or nuclear-powered weapon systems.

The announcement is framed by some analysts as a strategic "power move" intended to achieve reciprocity with near-peer adversaries, potentially forcing them into arms control talks ahead of the New START treaty's 2026 expiration. U.S. intelligence has previously indicated suspicions that Russia and China may have conducted low-yield tests, and Russia's recent test of the nuclear-powered Burevestnik cruise missile adds to the geopolitical context.

However, the initiative faces strong opposition, with critics warning that resuming testing would be strategically reckless, destabilizing global nonproliferation efforts, and could prompt other nuclear states to expand their own testing regimes. While proponents argue it ensures optimal weapon functionality and national security, the overall market sentiment is mixed with an uncertain tone, reflecting the significant geopolitical risks involved.
