The panic about Trump’s announcement that the U.S. would begin nuclear tests after 33 years of not doing so was unwarranted. From Moon of Alabama at moonofalabama.org:
A Truth Social tweet by U.S. President Donald Trump on nuclear weapons has led to some confusion and, as I assume, misinterpretations.
Donald J. Trump @realDonaldTrump – Oct 30, 2025, 1:04 utc
The United States has more Nuclear Weapons than any other country. This was accomplished, including a complete update and renovation of existing weapons, during my First Term in office. Because of the tremendous destructive power, I HATED to do it, but had no choice! Russia is second, and China is a distant third, but will be even within 5 years. 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. Thank you for your attention to this matter! PRESIDENT DONALD J. TRUMP
The Washington Post interprets it as a test of nuclear warheads:
Trump directs Pentagon to test nuclear weapons for first time since 1992 (archived) – Washington Post
The president said he wanted testing to occur “on an equal basis” with Russia and China. The Kremlin condemned the move, and there was no indication of when tests might take place.
President Donald Trump on Thursday morning said he directed the Pentagon to begin testing nuclear weapons “on an equal basis” with Russia and China, an apparent attempt to flex the United States’ military might ahead of a high-stakes trade meeting here with his Chinese counterpart, Xi Jinping.
Trump’s announcement on Truth Social signaled a reversal of decades of United States nuclear policy that could have far-reaching consequences for relations with U.S. adversaries, though his post included very few details about what the tests would entail. The last nuclear weapon test in the United States was held in 1992, before President George H.W. Bush implemented a moratorium on such exercises at the conclusion of the Cold War.
Trump wrote that the process would begin immediately and was in response to other countries’ testing programs.
The president posted about resuming nuclear weapons testing as his helicopter, Marine One, was in the air on his way to meet Xi at Gimhae Air Base.
The Trump tweet is wrong in that it asserts that the U.S. has more nuclear weapons than any other country. All public sources say that Russia with about 4300 nuclear warheads has slightly more than the United States with about 3,600. China has about 5-600 nuclear warheads and is building up its nuclear weapon arsenal to about 1,000 warheads by 2035.
