You know, I think a big 'thing' in the glee in certain MAGA quarters going on is that the US hasn't seen actual 'warfare' since May 1865 (Battle of Palmito Ranch, TX). Yes, there were Pearl Harbor and the warfare in the Aleutians during WWII, but those were not states at the time nor was there the devastation that the countries in Europe & Asia experienced. So we are ignorant to the reality of the civilian costs of war, it's too far removed from us.
Europe and Asia still have survivors of bombings, alive to tell the tales. There are probably still remnants of buildings and God knows there are battlefields aplenty. We here are 170+ years removed from that. As moving as the USS Arizona Memorial is, there is somehow a difference between military deaths and civilian deaths during a war. We expect military casualties, but because we didn't suffer many civilian casualties on US soil we're unable to empathize with the people we are currently putting such terrible danger.
Civilian casualties in the US in WWII 1500, civilian casualties in the UK in WWII 70,000. Not really comparable, are they?
