That's exactly why 'expansionist' regimes were ready to start some next war, being eager "to get some extra land" as a result of said war.
The current war is different: this is the war that started not out of appetite towards foreign lands, but, basically, out of primal fear, the fear concerning safety. The West was failing at self-reflection and was completely oblivious about their own actions being treated as crossing a real red line for Russia's safety.
You may scare a wandering bear away, but driving it into a corner is both stupid and fatal.
