I believe Bulgaria should generally not be lumped together with Slovakia and Hungary though.

That being said, the war has to end. Pretending like it could go on indefinitely, as Biden and Europe did, is infantile.
How? Trump rather infamously stood up at a press conference and said, in effect, he trusted Putin more than his own intelligence agencies. The only real anti-Russia thing done during his administration that I can recall is the Magnitsky Act, but the clear impetus for that came from Congress and Trump only very reluctantly signed it.
Words are not policy.

Nord Stream 2: Biden waives US sanctions on Russian pipeline
Yeah... Trump isn't dictator of the world. The only way he can make peace in Ukraine without consulting Ukraine is to persuade Russia to withdraw. (Which, if he did, that would be great... but I'm not holding my breath.) Other than that, the most he can do is stop supplying Ukraine with US weapons and intel, and let Ukraine decide what to do in the new situation.
And, having the EU pay for reconstruction? The EU is not under Trump's orders. They may chose to help pay for Ukrainian reconstruction, if they choose to do so, but it won't be because Trump "had" them do so.

Furthermore, there is a clear danger that Trump will make peace in Ukraine (without consulting either the EU or Ukraine) and have the EU pay for the reconstruction. And he'll possible resume friendship with Russia after the EU-Russia relationships have been ruined.
The EU should stop playing the games of the US, which change every four years. It should develop its own foreign policy and stop being taken advantage of. Rule #1: Never get involved in a war that is promoted by the US. All "friends" of the US have been screwed over in various proxy wars. Kissinger even said "to be a friend of the US is fatal".
