I'm going to leave the whole first part alone, just so this doesn't devolve TOO far. >> As a thought exercise: how much longer do you think the world will abide nuclear weapons? Are they just here forever? They're probably here as long as there's a desire to utterly wipe a large area off of the map. Maybe the USA doesn't want them anymore, but many, many other countries want them and will continue to work towards getting them. Having them gets you a seat at the power table, and people have to listen to you. Even if they're not used, they're an extraordinarily valuable tool.
