You excused the behaviour of Soviet forces because the allies carpet bombed German cities. From hindsight we can say both tactics are useless. Contrary to the west Russia has not learned anything from WW2. They flatten cities and target civilians with the theory it will undermine the Ukrainian will to fight. With their numbers a competent military would have won this special mission. It is a classic case fighting WW2 in 2022. WW2 the British bombed German cities first, the strategy worked because it diverted the Luftwaffe away from military targets. Had to Luftwaffe concentrated on the British radar stations and airbases the Battle of Britain might have ended differently. Churchill needed to increase the British will to fight in 1940. In this the Blitz served its purpose, a considerable number in the British parliament didn't rule out a negotiated settlement.
