Supporting Ukraine = being against peace?

I need help refuting this talking point because it is driving me mad and I cannot articulate myself in a way I want.

I am 100% on board for America to keep supplying and funding Ukraine. It is absolutely imperative to me that Russia understands that they cannot invade another country and get away with it.

But the lexicon has certainly shifted. American conservatives being against funding Ukraine is one thing (it seems like conservatives want to give up all American soft power and alienate allies, for reasons I don’t know), but the accusation is now that, if we don’t stop supporting Ukraine, we are against peace in the region.

For some reason, giving Russia carpe diem is suddenly the most peaceful solution, when Ukraine is the victim in this situation. We have been friendly with Ukraine for decades and have a concentrated effort to preserve their independence.

Can someone help me understand how to better my pro Ukraine arguments? And when did American conservatives become simps for Russia?
