I read the whole thing and in my head all I can see is a bunch of people in suits trying desperately to stuff a load of screaming, thrashing cats back into a burlap sack.

I wish nuclear weapons weren't a thing. I wish they had never been discovered, or simply were a scientific impossibility. But they were discovered, they do exist, in multiple nations, and that can never be undone... It's so hopelessly naive to think that countries like China and Russia wouldnt simply "play along" with disarming and then say "lol we didn't really!" when the thread of M.A.D is nullified. But then, let's face it, the US would likely do the same so it would all be a complete charade.

The Nuclear Threat will end (assuming not in war... Haha...) when anti-Nuclear/anti-ICBM technology neutralises the threat and makes them more difficult to deploy than is worth it. The sort of global cooperation that would be needed to disarm just doesn't exist, and if it did exist, you wouldn't need to disarm, because there would be no threat of war anyway.
