Now Trump is going to increase tariffs on Canada and Europe because he's angry Canada is taking its business (and its security concerns) elsewhere, not just cheerfully submitting to being bullied?

You antagonize someone until they want nothing to do with you, and then, when you see it's pushing them away, you keep threatening them and insulting them to make them come back. Does he see this working?

It's elementary school-level psychology, but Trump doesn't understand it.
