Look it up, in 2007 G.W.Bush invited Ukraine and Georgia to NATO. Also look up PNAC. Unfortunately, there was little interest from the U.S. side to end the cold war - they had to be a "world policeman".

Yes EU leaders called for deescalation, that is true. But the U.S., the most important NATO member, did not. There is a 2018 report from RAND that suggests Ukraine should be used as a tool to weaken Russia.

The Ukraine conflict, although there is a contribution from other causes (russian and ukrainian nationalism), is a proxy war between U.S. and Russia, a continuation of the cold war.

I don't disagree with you on Russia, but the US and EU (currently) is unfortunately not interested in deescalating.
