On one hand he wanted to "break up nato" and on the other he wanted nato to collectively spend 100s of billions every year to militarize. Broken clocks and politicians who take every side of every argument are right every so often.
Those positions are not mutually exclusive. Rather, it's more of an ultimatum. "Spend more on our collective defense and reduce your dependence on our adversaries, or we'll no longer be allies."
Yeah, exactly. Trump's position on NATO was, as his position on damn near anything else, unintelligible gibberish. There was no constant except a pervasive affectation--colouring his rhetorical posture on everything he ever discussed--that the US was, in some ineffable but profound way, being "screwed".
