US dropped bombs on Hiroshima and Nagasaki to instantly end WW2 which otherwise could take years, costing the Allies thousands of their own soldiers. Japan could have surrendered before the bombs but they chose not to and preferred to fanatically fight to the last soldier. Soviets put the lives of thousands of their own citizens at risk… essentially out of curiosity.
But this is not the point of what Burkov said: what he describes is the utterly degenerate nature of the Soviet system which was oppressing primarily its own citizens and blackmailing Western powers to be allowed to continue the oppression. Burkov knew what he was talking about, because he was a Soviet citizen himself. And the similarities to today’s Russia are numerous.
