I think it's a good thing Trump is forcing Europe to up its defense spending, we have piggy backed on the safety of the US military for too long.
We don't need the US to beat Russia, in fact, without the US putting restrictions on how the war is fought (like not attacking russian oil refineries), we can cripple Putin much faster.
That said, his behavior towards Zelensky is disgraceful... I'm all for the tough negotiations but this was just childisch and disrespectul from the Americans. JD Vance was making arguments like a child... Most of europe sees all of this as a temporary phase though, just wait out trump, 4 years at most.
