"The irony of Comrade Pr00ne's disparagement of Chastise is that the main beneficiary of the operation was the Soviet Union's Red Army, as was the case with much of the RAF's Strategic Bombing Campaign."
In much the same way that the Red Army campaigns were to the benefit of those landing in Normandy.
We were all on the same side (then) and the ability of the Allies to keep up pressure on all fronts (East, West, South, SW and bombing) meant the Germans couldn't benefit from their internal lines of communication. They HAD to fight everywhere and as they were ground down the gaps started to appear which eventually led to total collapse in all directions in '45.
