I agree that the only listed choice would be the ME-262. The V2 the second choice but after watching Scud’s smacking Israel and Saudi Arabia, the V2 alone was not enough. These rockets are just to random to make a difference.
However, I agree about the Atom Bomb, as long as the US was on track to develop it by 1945 and the German’s weren’t, the end would have been the same, eventually. Also remember both the UK and US had flown their Glouster E28/39 and Bell XP-59 prototype jet planes by 1942. The allies certainly would have worked hard to develop jet fighters of their own to counter the Germans.
The Germans flew the first Jet plane the Heinkel He 178 on August 27, 1939. A few days before Poland. At that time they were to busy to anything but tinker with Jets but what if they had thrown the full weight into them?
German economic production could only do so much.
