That’s insane. Absolute hogwash.The U-Boat was carrying uranium oxide, not a fissionable material and had no plutonium onboard. That is like saying ancient Egyptians were on the verge of making a radio because they developed copper wire. The Germans were a long way from developing any type of nuclear weapon and Oppenheimer and his boys absolutely knew this to be the case.
If you honestly think that the Axis powers were not pursuing the same goals as our forces you are seriously deluded. Were these people any less intelligent? Were they less motivated?
It was a footrace, and our side was lucky enough to get there first!
