So the answer is to let every country develop and arm themselves in fear of being attacked. Sounds like a recipe for nuclear hell on earth coming to a town near you.
You just need some crazy mofo like the truman and it's on. Luckily those were the first nukes but imagine the japs and everyone else had nukes, it would not have ended well for our race. So all it is going to take is one crazy ******* to drop one and it's game over for the rest of us.
The end result will be no different if everyone hides their nukes... So whats your point? At least if everyone knows who's got what, you'll know who not to piss off
