You don’t have to go that far back, or even leave the shores of the USA. The 50s and early 60s, the Red Scare years, were chock full of lynchings, leftists jailings, black leaders being assassinated (the CIA assassinating a president?), militarism, and imperialism. They had wee kiddies practicing cowering under our desks as school safety events in case of nuclear war. Actually, except for the addition of the climate starting to kill us, little has changed in 60 years. It may seem worse now since the real left has been neutered and replaced with whatever the DSA and their ilk pretend to be.
Check out these pictures of Raqqa after US and NATO bomblngs freed them for democracy. 70-80% of buildings were destroyed. The “official” UN civilian death toll is listed as 4,118 but some estimates say the number could be 10x higher as the city lacks the resources to sift through the rubble. https://www.boredpanda.com/before-after-war-photos-aleppo-syria/?utm_source=duckduckgo&utm_medium=referral&utm_campaign=organic
