The real reason why the reactions are different this time is West Europe, not Ukraine. They are fueled more by pragmatic self-interest than by moral concerns.

The real reason why the reactions are different this time is West Europe, not Ukraine. They are fueled more by pragmatic self-interest than by moral concerns. For a long time, West Europe sought good relations with Russia and benefited from trade. That changed when Putin attacked Ukraine. The war hit too close to home, and West European countries could no longer trust Putin's intentions. The primary reaction was a sudden increase in military spending. As a secondary reaction, West Europe gave ok to stronger sanctions that were already supported by East Europe and the US.
