Yes.

During the cold war there was US bombers flying in the sky of USA 24/24 to be ready to counter-attack a nuclear offensive...

Problem is that lot of these bombers crashed or misteriously disseapeared, which means there is a LOT of nuclear bombs lost somewhere in the US and which could explode any day or contamine the water and the earth...

I got some interessing documentary about it, but i need to find it back.

Plus, countries like Iran and North Korea are still dangerous and they all have nuke...

And i'll not even mention US and Russia have enough bombs to destroy the earth 200 times ....
