Trump’s trip to Britain comes after a contentious NATO summit in Brussels, after which Trump claimed, without evidence, that he’d convinced other NATO countries to dramatically increase their military spending.

President Donald Trump: “The people have stepped up today like they’ve never stepped up before. And remember the word $33 billion more they’re paying, and you’ll hear that from the secretary general in a little while. He thanked me, actually. He actually thanked me. And everybody in the room thanked me. There’s a great collegial spirit in that room that I don’t think they’ve had in many years.”

French President Emmanuel Macron refuted Trump’s claims, saying countries had not agreed to increase military spending beyond the 2 percent increase by 2024, a plan that had already been brokered under the Obama administration.
