Take that, Canada and Camelot.

America’s bulldozer president plans to raze the Kennedy Center and rename Lake Ontario if he’ s frustrated in one of his top legacy projects and his latest trade war.

The pair of threats made Tuesday seem absurd. But they epitomize a driving impulse of Trump’s second term: the belief that nothing can stand in his way.

And when reality doesn’t please him, he invents his own.

The twin episodes also raise the glaring question of why Trump fixates on such trifles even as his war in Iran grinds on and Americans despair at high prices for food, fuel and housing ahead of the midterm elections.
