Trump scares the Europeans. He doesn’t scare them because he expects them to pay for their own defense. All of his predecessors had the same expectation. He frightens the Europeans because he ignores their rhetoric while mercilessly exposing their true policy and refuses to accept it. They are scared that Trump intends to exact a price from them for their weak-kneed treachery.
Intends to exact a price. That is what Trump’s political enemies really object to about him.
