>What exactly is NATO without the US? For starters, it's still a lot bigger than Ukraine. Ukraine have successfully resisted Russian invasion for a couple of years, initially without the modern Western weaponry they now have (limited) access to. And they've recently pulled a switcharoo and actually invaded Russia a bit. Even if the US decided to pull out of NATO, should Russia invade a NATO country then Russia is getting bounced out on its collective ear. Would the US leaving vastly weaken NATO? For sure. But is NATO still fit for purpose without the US for the remaining states? Yes. A worse scenario would be if the US and its contractors pulled out of everything, like the F-series plane agreements, the shared nuclear arsenal with the UK, Five Eyes etc. That would be catastrophic. But those left behind would still have enough to defend itself against Russia.
