According to The New York Times, as per Trump's speech at NATO, he also behaved like an asshole by telling the NATO countries to pay more, something that's not required as per NATO's agreements, and he refused to endorse Chapter 5 of NATO, which says that if any one country in NATO is attacked, they're all attacked.
