Yeah... NATO is DEFINITELY not sending troops to Ukraine basically ever at this point. Because they increasingly need to be worried about both russia AND the us attacking them.
Well, that's the problem with NATO, it was always US interests first and European interests second. Whenever those two diverged, the Europeans just had to sit on their hands (that was the deal, that is why defense spending was not a priority)...but this time it is different: it has proven existential for Europe, regardless of whatever direction the wind may be blowing at that one time in the oval office.
Watch the interview. Trump is scared shitless over the potential of WW3 and UK and France have nukes. If NATO (less US) decided to do something in Ukraine, the most Trump would do is impose tariffs, which is something he was going to do anyway.
