Earlier quoted context omitted.
Yeah, sure. But the US chooses who it integrates with militarily. An alternative approach would have been to say "hey, yeah we can see why you'd want to join - but this will foment tensions with Russia, so you can't". That is the kind of diplomacy would have prevented Russia from invading its neighbours. It would have been difficult to get worse outcomes with that approach than what the powers that be managed to get…
The only thing that would have changed is that Russia now also could invade the baltic states. Why do you think Russia would not have invaded Ukraine if the NATO had not been expanded?
Ukraine is a great example of what US support does - if the US had told them that they're on their own, Ukraine would have just gone with whatever Russia wanted diplomatically.
Instead, a lot of Ukrainian's are dead, they've lost a double-digit percentage of their country, the west is hell-bent on destabilising the leadership that controls the world's largest nuclear arsenal, it looks like we're escalating into a WWIII style situation because the US deterrence is failing and Ukraine is STILL likely to end up having to do what Russia wants. Technically not maybe because they've lost the territory that Russia was most interested in.
The US shouldn't be involved in militarily organising Eastern Europe. It has not helped, it seems to be making war a certainty.
