The use of the term 'terror bombing' indicates a lack of objectivity. An interesting appraisal of the Dresden bombing can be found here: The WWII Bombing of Dresden: Propaganda and Mythology. By: Michael W. Kramer
I already stated that the Feb 45 Dresden raid (the one the OP is asking about) was operational level bombing, it wasn't designed to get the Germans to surrender, not designed to do anything more than cause mass damage to impede movement of troops and logistics, cause traffic buildup, cause a major regional emergency requiring aid to be delivered to the city, all while in conjunction with a massive Soviet offensive aimed at crossing into the eastern German border. In that, I actually think it would have been worthwhile if it had been conducted about 2-3 weeks earlier, while the Soviets were still launching their offensive in the area, which by the time the raid was actually conducted, was already over with, making the raid kind of superfluous.
