Interesting information on why was Dresden destroyed.
Dresden was obliterated in order to intimidate the Soviets with a demonstration of the enormous firepower that permitted bombers of the RAF and the USAAF to unleash death and destruction hundreds of kilometers away from their bases, and the subtext was clear: this firepower could be aimed at the Soviet Union itself. This interpretation explains the many peculiarities of the bombing of Dresden, such as the magnitude of the operation, the unusual participation in one single raid of both the RAF and USAAF, the choice of a “virginal” target, the (intended) enormity of the destruction, the timing of the attack, and the fact that the supposedly crucially important railway station and the suburbs with their factories and Luftwaffe airfield were not targeted. The bombing of Dresden had little or nothing to do with the war against Nazi Germany: it was an American British message for Stalin, a message that cost the lives of tens of thousands of people. Later that same year, two more similarly coded yet not very subtle messages would follow, involving even more victims, but this time Japanese cities were targeted, and the idea was to direct Stalin’s attention to the lethality of America’s terrible new weapon, the atomic bomb. Dresden had little or nothing to do with the war against Nazi Germany; it had much, if not everything, to do with a new conflict in which the enemy was to be the Soviet Union. In the horrible heat of the infernos of Dresden, Hiroshima and Nagasaki, the Cold War was born.
