I don't accept the subjectivity w.r.t. "perceived reality". Russia's military unreadiness was one of the big reasons I consider the invasion irrational, and I put the blame squarely on Putin because he could have gotten accurate reports if he wasn't such a bad leader. You are responsible for your perceived reality, and part of rationality is acting in a way that it matches real reality.

(But yeah, clearly his actual goal was to increase his personal prestige. Is that not common knowledge yet?)
