...the official US definition is something to the effect of "Terrorism is the calculated use of violence or the threat of violence to attain religious or political ideological goals though intimidation, coercion or instilling fear."

What the Germans did to Coventry and what the British did to Dresden were both inexcusable, as far as I've heard. Two historical centres totally levelled.
