The same thing they've been doing. The U.S. isn't supporting Ukraine nearly as much as people make it out to be. All we did was spend money on U.S. contracts, and send mostly old munitions. The majority of all the aid ever going anywhere was blocke/halted. Of $180b that was supposed to be sent beteen 2022-2024, $100 billion still has not arrived. Trump supported Russia from the start, and legislature held off everything they could waiting for him. And a large amount of the population apparently wanted Russia to expand as well.

Europe has a strong interest in keeping Russia from taking over Ukraine. Ukraine will only be the first European country to fall if Putin takes over Ukraine. There is a reason that Poland and others have been building up their military. Yes, the purported deal being reported "only" involves a surrender of land and not a complete takeover, but anyone with half a brain knows that there is no way that such a deal will satisfy Russia. It would be only a short-term "peace" to allow Russia to regroup to take another run at it. There is no way Ukraine would agree to this "deal" because it would only worsen their position. Better to fight without the U.S. than to roll over to allow Russia to regroup and strengthen.

There is a lot variation but it comes through that Europe is the biggest supporter now.

US Support dried up a long while ago.

Europe has done more for Ukraine than the US has. Under Biden, there were endless delays and shortfalls, largely caused by the Republicans in Congress, and Trump has done even worse, since he very evidently wants to hand over Ukraine to his master Putin, despite all the fake huffing and puffing.
