I'm asking for someone to describe ANY scenario (for the UK) in which one would be effective or appropriate. I'll even accept a scenario where having them is useful just as a deterrent.

Come on guys... this shouldn't be hard, should it? I mean, people are arguing very heavily in favor of having them so I assume someone must be able to offer some reasoning.

Which country or group has nuclear weapons, or potential nuclear weapons, and would be deterred by our own nuclear weapons, or would be a viable target for actual nuclear retaliation.

Answers on a postcard. Anyone.
