This "Manhattan Engineering District" project is a risky scheme, an expensive boondoggle that could destroy mankind. I don't know how the family of Prescott Bush convinced FDR to do this, but the Bush Family Criminal Conspiracy should be made to face the most severe of charges forthwith. For all we know, a fission reaction could run out of control and burn off our atmosphere!
FDR needs to root out the irresponsible, 'swarthy'--and probably fascist--cabal within the Pentagon that started this fiasco and get back to work helping Uncle Joe crush the hun.
FDR needs to share the technology with our comrades, the glorius ussr. {OH, nevermind, our friends will take care of that after we know it works}.
