Gee you sure have a lot of respect for the USA don't you? I guess you don't know that Trump holds all the cards in NATO.
I can tell you right now that NATO has burned a bridge behind them now they could not afford to burn. Just wait until they need the US for something, like some of that Iranian oil your lives depend on.
With a snap of our fingers, Trump could cut all of Europe off from oil and gas next winter leaving them begging for supplies from Russia, the very country they are sorta, kinda opposing with Ukraine.
In fact, if we wanted to, we could probably disrupt the Gulf-stream which supplies warmth to the UK and northwestern Europe, plunging all of you blokes into a perpetual nuclear winter.
And never forget, 500 psychiatrists stated that Trump is a crazy bastard who could go off at any time.
