Yes, there are many people who enthusiastically support US intervention in Ukraine, just as there were many Americans who enthusiastically supported US intervention in past conflicts around the world (Vietnam, Afghanistan, Iraq, etc.). I think it is likely that the time will come when the waste of resources and lives becomes obvious, and most Americans regret US involvement in the Ukraine conflict. As they say, “time will tell”...
Those were mistakes because we involved our troops in nation building. In Ukraine, they themselves are ferociously defending their own country with no US troops directly involved. We are just sending weapons, which are used by Ukraine to destroy the Russian military.
