Yes, as I have already said, Iran et al are a new kind of opposition and must be treaty differently. But the debate is not should we nuke Iran. The question is 'should the UK replace it's nuclear detterrent?' and if 'yes', what with?
Now with the arguments presented here, over what status the UK would have if it did give up it's detterrent, I can not see how you can justify it's removal.
