He wrote a book in 1940 where the US became the first nuclear power. In his world it wasn't a bomb, it was radioactive dust dropped from a plane that would kill everyone. Keep in mind this is before the Manhattan project. In the book, the guy in charge of the project knew other nations would developed it soon and the effects would be bad (cold war) so he staged a coup. He had all of his bombers circling every nation on the planet, and threatened to eliminate them if they didn't agree to give up their air force capabilities. if I remember, he had to make an example of someone (Hiroshima) before the rest fell in line. He hated it, but knew he had to do it to maintain world order.
Wonder how the world would look if we took that course after ww2.
