Trump would abandon our NATO partners over “unpaid bills”, and wouldn’t defend them. No one should be surprised that Trump would engage in “pay to play” tactics, it’s in his DNA. Maybe our NATO partners should have set some pay to play rules when they came to the USA’s defense for the first and only time that Article 5 was ever invoked in NATO history, after the 9/11 attack on America, and remained by our side for 20 years. No amount of “back dues” is an equivalency for a comrade in arms by your side willing to spill their blood for you, (and they did).
