It is the third year of war, and Russia is bombing Kharkiv.
We often try to explain away senseless evil with insanity. He’s a maniac! What did you expect? And the war with Ukraine is so terrible and senseless and is causing such huge damage both to Ukraine and to Russia itself that there is a temptation to try to attribute it all to the insanity of one man, or, at the very least, one man and a group of his closest associates.
There’s no getting away from the insanity. There can be no rational explanation for this behaviour. Even if Russia secures an overwhelming military victory, which is unlikely, the country would still lose in economic and diplomatic terms, not to mention its terrible human losses.
