The US sets the pace, and the EU has no choice but to react at that pace. In Trumps world view there are no allies, only exploitable resources and enemies. International relations erode quickly when souvereign countries are threatened to either bend the knee or be treated as an enemy.

This is a train wreck from beginning to end, with only one winner: Trump.

It was stupid to call for an impeachment vote in the first place, because it had zero chance to succeed. It’s quite lame as a symbolic gesture too, because a failure is a failure in the books no matter what the intentions are. And you put your own party members in a position where they can only lose either way. This is terrible from a political strategy standpoint unless your explicit goal is to divide the party, which in turn weakens the party even more. A sad and unnecessary shit show all the way. The only hope left is that Trump dies laughing.
