Trump Proposes Resuming U.S. Nuclear Testing: Implications and Reactions

President Donald Trump has called for the United States to resume nuclear weapons testing, a significant shift from a three-decade moratorium that began after the last U.S. test in 1992. This announcement, made via a post on Truth Social, suggests that the U.S. would conduct tests "on an equal basis" with other nuclear-armed nations, specifically citing concerns over advancements in nuclear capabilities by Russia, China, and North Korea.

The U.S. conducted its last nuclear test at the Nevada Test Site on September 23, 1992. Since then, the country has relied on computer simulations and scientific experiments to ensure the reliability of its nuclear arsenal. The Comprehensive Nuclear Test Ban Treaty, signed in 1996 but never ratified by the U.S. Senate, has largely governed international nuclear testing norms, with only North Korea conducting tests since the 1990s.

Experts have indicated that resuming nuclear testing would require substantial financial investment, with estimates ranging from $100 million to $140 million per test. The logistical challenges are also significant; the Nevada Test Site would need extensive preparations to accommodate testing after years of inactivity. Corey Hinderstein, a former official at the National Nuclear Security Administration, noted that a new vertical shaft would be necessary for testing to avoid disrupting other operations at the site.

The announcement has drawn widespread criticism from various quarters. Nevada Representative Dina Titus expressed concern over the loss of expertise within the National Nuclear Security Administration, stating that many skilled workers have been dismissed or furloughed. Critics argue that resuming testing could trigger a new arms race, with other nuclear powers feeling compelled to follow suit. Daryl Kimball, executive director of the Arms Control Association, warned that Trump's proposal could undermine global nonproliferation efforts and provoke strong opposition domestically and internationally.

Trump's comments have prompted mixed reactions from government officials. Defense Secretary Pete Hegseth suggested that resuming testing could be "responsible," while Vice Adm. Richard Correll, nominee to lead the military's nuclear command, indicated uncertainty about the specifics of Trump's intentions. Meanwhile, the Kremlin has warned that if the U.S. resumes testing, Russia would respond in kind, potentially escalating tensions reminiscent of the Cold War.

• “Restarting the U.S. nuclear testing program could be one of the most consequential policy actions the Trump administration undertakes — a U.S. test could set off an uncontrolled chain of events, with other countries possibly responding with their own nuclear tests, destabilizing global security, and accelerating a new arms race,” — Daryl Kimball, Executive Director, Arms Control Association

• “If all you wanted was a stunt — to say okay, you set off a nuclear explosive, don’t worry about the data — you would probably take one of the weapons out of reserve, strip it down somewhat and then just set it off,” — Ernest Moritz, Former Energy Secretary

As discussions continue regarding the feasibility and implications of resuming nuclear testing, the situation remains fluid. Trump's announcement has reignited debates over nuclear policy in the U.S. and could have far-reaching consequences for international relations and global security. The potential for a renewed arms race looms large, as both allies and adversaries closely monitor developments in U.S. nuclear strategy.
