On Oct. 30, in one fell swoop — a single post on Truth Social — President Donald Trump seemingly undid decades of American nuclear policy and international diplomacy. In reaction to Russia’s announcement of a component test of its new nuclear missile, Trump called for a return to US nuclear weapons testing for the first time in over three decades. He framed it in his usual tit-for-tat style of diplomacy and emphasis on American dominance, but for me and for other nuclear experts, his call is a shocking and irresponsible threat to life as we know it.
“Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis,” Trump’s post read. “That process will begin immediately.” No further details were given.
The ambiguity of the statement opened the door to a horrifying range of possibilities. What this would accomplish, or what it even means, no one truly knew in the moment. Trump administration officials have since told media outlets that the testing will not include explosions. Nonetheless, experts have reiterated that there is no strategic reason to continue nuclear testing. And nuclear watchers have debunked the misinformation in Trump’s statement, calling into question whether the new nuclear weapons Russia boasts of are even useful. The Kremlin itself pointed out its tests “cannot in any way be interpreted as a nuclear test,” BBC reported.
In addition to being ambiguous and baseless, the statement was also wildly unprecedented. No nuclear power has carried out an above-ground explosive nuclear test in over four decades, and the last underground test was carried out in 2017 by North Korea. The only outcome of a revival of regular nuclear testing would be an increase in nuclear risk and an alarming acceleration of the new arms race — something the world has not felt since the Cold War and hoped to never feel again. It seems that the Trump administration, fundamentally, cannot learn from the lessons of history.
