Saw the movie. Liked it but was actually too lenient on Oppenheimer. He had multiple affairs—not just one—during the 40s and 50s.
If he had been anyone else, he would have lost his clearance a long time before he actually did.
I actually admire him as a scientist. But you just couldn’t screw randos and hang out with Communists and expect the government not to notice in the 50s.
The question amongst the shotcaller brass was about the use and the scientists had little to do with that as you know
Some wanted a warning blast over water somewhere
But Stimson and Truman said no
Prepare for two blasts
Part of the reasoning was we only had so many bombs and warning the Russians
Most don’t know the bomb was started to get ahead of Germany who knew would eventually make one
Even the japs were working on a super weapon
They selected targets for population industry and lesser historical and cultural significance
