Quite the contrary. The three greatest scourges of the 20th century — Nazism, Japanese militarism, and Soviet Communism — were defeated through war or continued military resistance. More were killed by Hitler, Stalin, and Mao outside of combat than died in World Wars I and II. War, as Sherman said, is all hell, but as Heraclitus admitted it is also "the father of us all." Wickedness — whether chattel slavery, the gas chambers, or concentration camps — has rarely passed quietly into the night on its own. The present evil isn't going to either.
