In my view being idiotically isolationist in the current situation in the world may be seen as short term anti-war, but in the long term means many more, even more severe, and much longer wars. Or even more risk of nuclear end games. Meaning Russia cannot be allowed to erase Ukraine.
So let's say the maga morons push Ukraine to surrender. Do you seriously think that means that Russia, China, Iran, and North Korea will be finished with their aggressions?
