Strong 'Putin won't invade Ukraine' 2022 vibes. Russia will stop with what they took in Georgia. Sorry, I mean they will stop with Crimea. Sorry, I mean they will stop with what they took in eastern Ukraine (plus we also have to give them Kherson). But yes, through history including with Russia, appeasing and giving land ends any future land grabs.
Putin has explicitly stated he's getting the USSR back together. He was worked in the eastern Germany KGB. His actions/current proof leans to he wants it all back. Zero leans to he doesn't. You argue you don't think he could take it. Again, that has nothing to do with it. The question is will he try/does he intend to, and everything points to yes. The same people said 'He won't invade Ukraine, he can't' that are now saying 'He won't try to take more, he can't'.
If that is all it comes down to, then yeah, I dont think he will try to take eastern Germany, no matter what he would like. Regarding the various attributions, I dont know what people you are talking about.
If protecting Germany is your final answer for why support the war, I think it is fine for the US to sit it out until article 5 is invoked.
It is kind of like expecting Europe to be ride or die in a US war with China over Taiwan.
