And if that didn't work, they were gonna take our our navy with sharks with frickin' laser beams attached to their heads.... ;-)
Seriously, there is a huge amount of revisionist history regarding the Germans and their real capabilities. Sure, they sketched a lot of neat ideas. They prototyped a few too. And even got a few projects into production soon enough to have a minor impact in the war. But all of those projects were tactical, not strategic.
The bottom line is that the Germans didn't have any war-winning projects even close to production. They were never close to developing an a-bomb, and they probably lacked the resources even if they had made a serious effort.
If you think about it, the Manhattan project was an incredible undertaking that was accomplished in about 3 years. In that timeframe, we developed two completely different A-bombs in parallel. A uranium bomb (little boy) that fired on a gun type principle, and a plutonium bomb (Fat man) that worked by implosion. The technologies and fissile materials (and the refining processes) were entirely different.
And until the Russians stole the technology, nobody else was close.
