“Hap Arnold, Arthur Harris, and Curtis LeMay”
To be fair, those attacks were done in retaliation, and “Bomber Harris” was vilified in the UK after the war for his bombing campaigns. It wasn’t until relatively recent he was accepted (sort of) and a Bomber Command” memorial was finally constructed.
Either they were war crimes by the definition that Patriot08 is using or they were not. If Sherman's actions he/she claims were war crimes were indeed crimes, then so were those of Arnold, Harris and LeMay. If Arnold, Harris, and LeMay are not war criminals than neither was Sherman.
