We are under no threat of that in the US. The UN is 100% ineffective anyway, they can't even stop or slow down Israel. Since the UN was created it's been the US that has been the major belligerent party across the globe. Our "policing" is the crime, we killed over a million Vietnamese people, over a million people in Iraq... we're the bad guys.
Any empire is the "bad guys" pretty much by definition, but there are still bad guys and worse guys. And Ukraine is very different from Afghanistan or Vietnam - it's a country that's genuinely asking for US military assistance against an external enemy that invaded it for openly imperialist reasons (annexing territory etc). Not just the Ukrainian government, but when you look at the polls, it really is a "people's war".
Now, that still doesn't obligate US to help. But it does mean that any military assistance that US does render to Ukraine can only improve its well-deserved "bad guy" image. If you truly believe that US did an evil thing by invading other countries, what better way to redeem yourself than to help someone who is being attacked by a bully just like you?
Agree, the us, and its allies have made some stupid decisions, but I would not be so sure there’s no threat from Russia. Putin may have already concurred the US by replacing its government by people that are owned by Putin, that vote and decide the way Putin wants them, and that are destroying the US and its economy so it can no longer be a leader in the world.
Israel did this long ago, not Russia. That's the threat. That's why our politicians vote the way Israel wants, that's also why they pass anti-free speech anti-BDS laws.
