I am not a fan of Oppenheimer. He was a necessary evil that Gen. Groves made the correct decision to employ, but only because he probably figured Oppenheimer wouldn’t be able to give data to the Soviets, because it would be easy to trace back to him.
He was a Communist who associated with Communists and had to “go dark” when he took the government jobs.
And someone I do trust on this aspect, Richard Feynman (who would be considered a Libertarian but not a Conservative) said that all the handwringing about the bomb within the Los Alamos scientific team back then that we talk about today is completely overblown. He said there was almost none of that at the time.
Everybody had a job to do, and they did it. We were at war, and even the egghead scientists knew it.
I agree with Feynman on that. The hand wringing is a form of virtue signaling and self loathing guilt liberals are good at.
