I think EU federation is pretty good, but I feel very dumbfounded every time dumb decisions that do not benefit member states are made, too much empathy too early I guess.
I wouldn't say so. The first years of the largest war in Europe since WWII have shown that a leaderless EU is incapable of making important decisions crucial to its own survival, as a fallen Ukraine would have led to a divided EU where many countries would be governed by authoritarian fascist regimes, such as the one in Hungary led by Orban.
But it seems pretty obviously not very good at any real executive action. Which is, again, by design.
