...or to Nazis.
If Hitler had found the genie first....
And if NOBODY had found the genie, then WWII would've turned the Pacific red, and the cold war would have gone hot conventionally in the 50's and devastated half the planet.
In the Race for the Bomb the Nazis had the immense handicap of their racialist ideology.
A very large number, possibly a majority, of the scientists important in the Manhattan Project were refugees from Nazi Europe. With other policies many of them might have been happy to work for Hitler.
There was also a strong undercurrent in Nazi ideology of disdain for “Jewish science,” which was basically all advanced physics.
I am amazed by the number of people who don’t seem to realize we owe the comparative peace since 1945 mainly to the Bomb. As you say, without it we would probably have had WWIII in the fifties.
And possibly IV, V and VI by now.
