Nah, the concept of appeasement doesn't apply here because the nature of the war is security competition between Russia and NATO with NATO having been the aggressor encroaching on Russian border while engaging in violent invasions of states like Yugoslavia and regime change operations including violent coup in Ukraine. You can stop lying about the causes of the war because the chief of NATO already admitted the real reason in plain terms:

The background was that President Putin declared in the autumn of 2021, and actually sent a draft treaty that they wanted NATO to sign, to promise no more NATO enlargement. That was what he sent us. And was a pre-condition for not invade Ukraine. Of course we didn't sign that. The opposite happened. He wanted us to sign that promise, never to enlarge NATO. He wanted us to remove our military infrastructure in all Allies that have joined NATO since 1997, meaning half of NATO, all the Central and Eastern Europe, we should remove NATO from that part of our Alliance, introducing some kind of B, or second class membership. We rejected that. So he went to war to prevent NATO, more NATO, close to his borders.

Now, it's obvious to anybody with even a minimally functioning brain that Russia has won the war, and the US will leave Europe out to dry. You warmongers deserve everything that's coming to you.
