Ukraine is a part of Europe, Europe responded. The US has heavy ties/trade relationships with Europe and so they responded, too.
I imagine if it was Taiwan that US/Europe would've sent aid to them all the same.
When it comes to Israel/Palestine and other conflicts the situation there is a lot more complicated when it comes to international relations/obligations as well as the duration and the history of the conflict.
That isn't to say, however, that any conflict isn't a tragedy and that hoomans shouldn't just stop it with the tribal, evolutionary-path inspired antics already.
