It's all nice to sit in your armchair discussing the moral limits to total war 70 years after it happened.
Agreed.
Few Allied leaders really thought the Germans could win a World War, although the Ardennes offensive drove the potential cost in men and material to the forefront. This event combined with the fact the Yalta conference had just ended and it is readily apparent the Brits and the Americans wanted to show Stalin they were cooperative allies with the Red Army. Dresden did have a build up of German troops and war material reported by POWs and even German soldiers in Dresden. The bombing also had the desired effect to help dissuade the Russians from taking more territory than was agreed upon previously.
If I had any questions it would consist of; "If FDR had died in October or November of 1944, what would the political environment of Europe look like between 1945-1992?"
