To quote Tacitus "They have made a desert and call it peace".
If the WALLIED actually had those numbers of aircraft, the bases large enough to operate them, the trained crews for them, the maintenance crews to keep them running, and the factories producing spares and new behemoths (Even if it's at a much lower level production then say B17s/B24s it's at least enough production to make up for losses from accidents, enemy action, and just the general nature of the B36s and a bit extra to slowly increase the operatable force size) in say mid 1942 to early 1943 do you think that might be enough to actually get the Germans to surrender? Say a minimum of say 300-400 B36s doing at least one sortie per day. So say 300-400 B36s each carrying 50,000 pounds in pounds per day/night continously.
Do the Germans have any aircraft or Flak guns that could reach them? If not how long to bring them into oeration.
Did the B36s have radar guided bombing sights? That would be a mass improvement over Nordens or just "Put a 1,000 B17s in a box each carrying four 500 pound bombs and have them release at the same time and hope for the best.
Of course all of this is incredibly ASB.
