I wonder who would be more destructive for Ukraine now. Trump would probably still try to "make a deal" that amounts to a Treaty of Versailles situation for Ukraine. Most if not all the Russian demands, Ukrainian demilitarisation and maybe partial integration with Europe without any territorial recapture or NATO membership. I don't see him fighting the war to the last Ukrainian though because he hates losers. He's been outspokenly vicious toward wounded/imprisoned/dead American soldiers and they're sanctified to his base. The state of the war is so bad 9 months before he'd be taking office that Ukraine has no heroic propaganda image for him to latch onto.

Biden on the other hand is just pure blood for the blood god. For his entire career, toward any vulnerable group, at any opportunity he was given to hurt someone. Gaza shows how feral he is and how little human life means to him. I think he'll ride the war out all the way to FABs raining down on Kiev. The full effects of the new conscription law will be realised, each new round of aid will sell off more of whatever Russia doesn't take, and in the end there will still be a Treaty of Versailles for Ukraine. Maybe he'd do a post-WW2 Canada and allow all the Ukrainian Nazis to be American refugees, something I don't see Trump doing because they're losers. If Trump tried, I could see liberals suddenly remembering what all the patches on the soldiers' vests mean and reverting to their pre-2022 stance on the Ukrainian military.
