Point being that the first and possibly second nukes were dropped stateside.
I read another article that made the claim that the bombs used in Japan were the last nukes ever dropped. Except there were decades of nuclear tests that followed around the world. They were the first, last, and only nukes used in combat. And perhaps it was their use in Japan that prevented their use in Korea.
If the nuke had been developed and not used in WWII, we likely would've seen it used by some nation at some point.
And just for history's sake, I'll remind readers that the Soviets almost launched a Mutually Assured Destruction attack against the US in the early 1980s because of some faulty equipment readings that indicated the US had "launched". The operator denied the readings he say and refused to launch. He was reprimanded but later his action was celebrated. It wasn't acknowledged until after the fall of the USSR.
