Why it would be a bad idea for the Trump administration to conduct a “rapid” nuclear test

The career of Brandon Williams, President Trump’s pick to run the National Nuclear Security Administration, does not give many clues about his priorities for the agency that safeguards the US nuclear arsenal. He served as a naval officer, co-founded a venture capital firm, and farmed truffles in upstate New York before spending two years in Congress as a Republican representative. (He lost his reelection bid in November 2024.) Like many of Trump’s nominees, he has had little direct interaction or experience with the federal agency he aspires to run. But for the Trump team, that may be the appeal of Williams. The search for an agency leader required a candidate willing to restart the US nuclear testing program, according to former Los Alamos National Laboratory director Terry Wallace: “That more or less disqualifies any recent director of any nuclear weapons lab.”

Restarting the US nuclear testing program could be one of the most consequential policy actions the Trump administration undertakes—a US 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. Yet, despite its significance to US national security, nuclear testing is not a subject Trump campaigned on, nor is it mentioned in the 2024 Republican Party platform. This silence on the issue is unsurprising: Nuclear testing is politically divisive and unpalatable to voters. When the first Trump administration contemplated a nuclear test in 2020, it faced significant backlash from Congress and nuclear experts. Trump’s appointee to the NNSA is likely to remain coy on the subject during his upcoming confirmation hearings.

Behind the scenes, however, close advisors to the administration are busy making the case for a new era of explosive nuclear testing to the national security community. Robert O’Brien, a national security advisor in the first Trump administration, was allegedly involved in the selection of Williams. Laying out a vision of Trump’s foreign policy priorities, O’Brien recently argued that “Washington must test new nuclear weapons for reliability and safety.” However, O’Brien’s claim is not supported by the agencies and officials tasked with overseeing the US nuclear stockpile…………………………………………………………………………………………………………………………………………………… more https://thebulletin.org/2025/02/why-it-would-be-a-bad-idea-for-the-trump-administration-to-conduct-a-rapid-nuclear-test/
