President Trump is leaving for his NATO summit in Brussels on Tuesday morning in an apparent good mood—and happy to take some preemptive shots at the world bloc. "Thank you to all of my great supporters, really big progress being made," Trump tweeted. "Economy is ROARING. Supreme Court pick getting GREAT REVIEWS. New Poll says Trump, at over 90%, is the most popular Republican in history of the Party. Wow!" And in multiple tweets, he reiterated a familiar theme, complaining that the US is shouldering an unfair share of defense costs overseas: "NATO countries must pay MORE, the United States must pay LESS," he tweeted. "Very Unfair!"
The sentiment already isn't playing well, with European Union President Donald Tusk firing off a zinger off his own Tuesday: “Dear America, appreciate your allies, after all you don’t have that many,” he said after a signing a cooperation pact between the EU and NATO, per Reuters. Trump will attend the NATO summit Wednesday and Thursday, with defense spending expected to be the toughest topic, reports CNBC. Then's he's off to Britain, Scotland, and finally to Finland for another high-profile summit on Monday—with Russian President Vladimir Putin. "So I have NATO, I have the UK, which is in somewhat turmoil, and I have Putin," Trump told reporters Tuesday, reports Politico. "Frankly, Putin may be the easiest of them all. Who would think? Who would think?"
