It wasn't the USSR that dropped two nuclear bombs (one uranium, one plutonium) on Japanese civilian targets when the Japanese were willing to surrender on the sole condition that they keep their emperor (a religious figure)
In the name of "stopping the spread of communism" the US overthrew popularly-elected governments, sent death squads into Latin America, and killed millions of civilians besides the ones they permanently maimed. This is besides the typical "make their economy scream" that kills civilians as well, in a way harder to quantify. Cuba is still the victim of this decades after the failed Bay of Pigs.
We have technically been in a state of emergency since the 50s with the undeclared Korean War, and for what? The permanent wartime economy hasn't benefited anyone besides the military-industrial complex. American imperial designs in Vietnam, Laos, Cambodia, Cuba, Yemen, Syria, etc. were all enabled by this escalation mentality and the crimes against humanity that were committed there are a permanent stain on humanity
