That loss of life is not enormous if you look at the overall graph of civilian and military war-related deaths throughout 20th and 21st century. It very obviously trended downwards, especially after the Cold War, before the Russian invasion of Ukraine which caused a spike. Then again, communism resulted in millions more civilian deaths in the same time period. The US impact on the worldwide death toll is often overstated for some reason, it's as if people are entirely unaware of events like Holodomor and The Great Leap Forward.
