Last weekend, I asked two British foreign-policy officials what had been the most troubling moment, so far, of President Donald Trump's world-destabilizing start to 2026. Both said (despite the British government's refusal to acknowledge this out loud) that it was the United States' seizure of the Venezuelan President, Nicolás Maduro, from Caracas, in the early hours of January 3rd. Trump "surprised us on the downside," one said. "Just not having had an inkling that Venezuela was coming," the other observed.
