“The last time President Trump vowed to halt a country’s nuclear weapons program, he held three face-to-face meetings with Kim Jong-un of North Korea, declared that the two men had developed a ‘great relationship’ and walked away empty-handed,” the New York Times reports.“That was in Mr. Trump’s first term. Not only did the diplomatic effort fail, but Mr. Kim immediately hit the accelerator on his program and today possesses roughly 60 nuclear weapons, by some estimates, as well as missiles that appear capable of reaching the United States — exactly the combination Mr. Trump had vowed to dismantle.”“For months now, proliferation experts have questioned whether Mr. Trump could also end up walking away from his efforts to check Iran’s nuclear program — especially now that he appears to be more focused on getting the Strait of Hormuz open than on dealing with Iran’s stockpiles of uranium, which are buried under rubble after the United States bombed them in June 2025.”
