My view is this. The world will never (despite treaties) get rid of it's nukes, and the treaty on our part regarding decommissioning could resume when all other nuke armed countries are at our numbers (as i said, never). Also, the fact that that the Soviets never invaded western Europe was no coincidence, the fact that Egypt, Syria, Iraq, Iran, Libya, Jordan and Pakistan have not completed their goal of destroying Israel is no coincidence, the fact that despite tensions there has not been full war between Pakistan and India (Kashmir clashes only) is no coincidence. And do you think that the Russians would have annexed crimea and violated Ukraine if the Ukraine had kept their soviet stockpiles ? I think not. In fact i'd say Mutually assured destruction is exactly what has thus far stopped a third world war. Regarding nukes, the only thing that we need to do is stop religious crazies like Iran getting them (as they have vowed to wipe another nation off the map), everyone else (including Pakistan it seems) can be trusted not to use them. (i leave the unique threat/non threat of North Korea aside for now).
