The reason the US government is helping Ukraine is to push back the tide of tyranny. Same as it has always done (Korean War, Vietnam War, Gulf War, etc.)
The world is always changing directions; either into the path of authoritarianism or freedom. While I agree that it's not always in America's best immediate interest to involve itself in these sort of things, it is definitely in the interest of people everywhere in the long term. First it's Ukraine, then Moldova, then Lithuania, Latvia, etc., until it reaches our door.
I mean, was WW2 that long ago? Don't you remember what happens when you let a bully take control?
