President Trump issued an “ultimatum” to European countries regarding the Strait of Hormuz after meeting with NATO Secretary General Mark Rutte at the White House on Wednesday.German news magazine Der Spiegel reported that Trump is expecting NATO members to help reopen the strait, which Iran closed in retaliation for the war Trump started without speaking to any of those NATO members. He’s also threatening to pull U.S. military support from any countries that don’t help reopen the strait.Trump’s demand is equivalent to an “ultimatum,” several European diplomats told Der Spiegel.“None of these people, including our own, very disappointing, NATO, understood anything unless they have pressure placed upon them!!!” Trump posted on Truth Social early Thursday morning, hours after his meeting with Rutte.This isn’t the first time Trump has begged NATO to help him reestablish a status quo that he disrupted. Last month, Trump claimed that other countries—such as China—depend more on the Middle East waterway than the U.S. does, and should therefore be leading the charge in reopening the bomb-laden strait.“I’m demanding that these countries come in and protect their own territory, because it is their territory. It’s the place from which they get their energy. And they should come and they should help us protect it,” Trump said. “Why are we maintaining the Hormuz Strait when it’s really there for China and many other countries? Why aren’t they doing it?”
