If 1 good thing will come out of this russian war is the firm realization globally that russia is a solid dictatorship still/again actively opposing democracy anywhere in the world, with absolutely 0 regard for its own population and generally being very, very far from typical western values on which they frown as subpar, weak and a threat.

There was some solid naivity not only in EU in past few decades, merkel et al completely ignored warnings from baltic members or Poland that russia can't be trusted yet. Current german leadership still doesn't treat this as their top urgency, they naively hope russians will get bored or scared from human losses and do just tiny glacial moves. This won't ever happen, just look at WWII, they still have the same mentality. They have to literally run out of equipment to stop at this point, they won't run out of men, not a country of 150 millions of which many are barely literate and fed propaganda every day.
