At the conference of allies in Yalta they were actually negotiated agreement about the mutual military actions. In particular, the Soviet command requested to support the offensive of the Red Army by air strikes. Speech went on also about the bombardment of railroad it was main in Dresden and Leipzig in order to hinder the throwing over of German reinforcements. But STALIN NEVER REQUESTED ALLIES TO BOMB THE CENTER OF DRESDEN. This was the initiative of command RAF (on that seen of Cherchil itself).
At the end WW2 there were examples when RAF and USAAF they helped the Red Army. For example the bombardment of Koenigsberg before the assault, which on Hitler’s order was converted into the unapproachable “city- fortress”. Or the bombardment of well fastened Berlin during April 1945 before the completing assault. The military necessity for these actions is caused doubts not in whom (although from the airstrikes in Berlin perished also ten thousand simple citizens).
But combustion of tens of thousands of simple Germans in the city, which had no military targets; therefore not it was protected BY AIR DEFENSE, no military aim it pursued. This barbarous action not a bit did not break the desire of Germans to resist. On the contrary, this gave excess occasion to the ministry of Goebbels to harden Germans. Which led only to the bitterness of war and the excess victims.
