It looks like the Brits are having a debate over whether they should replace their Trident nuclear missile system or not. I say, for their own sake, just decomission the bastard and don't replace it. If any of them are actually concerned about security, they know they've got more than a few at their disposal across the Atlantic. Furthermore, this sends a positive message to any would-be nuclear states, and eliminates a not-so-small point of hypocrisy in the British non-proliferation stance.

The real question here is whether this move could offer a credible incentive to another country to stay straight on nuclear weapons, a la the Missouri Compromise. I don't know that this measurably helps any other states, but hey, diplomacy doesn't always have to make sense.
