As far asI can see, advocating that everyone with nukes gets rid of them in order to lead by example is far from advocating nuclear proliferation.
Otherwise it's "you can't have WMD mr Korea, Iraq, Pakistan etc, but WE can and so can our freinds, Israel, GB, France etc" Do you guys see how arrogent and what a bunch of hypocrytes you sound! I wouldn't bloody listen if I was them. But I might if it was "You don't need WMD because we don't have them and come and have a look if you don't quite believe us! Now lets talk about helping to boost your economy and improve living standards for your people" They Might sirt up and take notice then might they not.
And if not,
Those players like USA , France, GB Russia etc. Should give up nukes along with everyone else. They have a vast tech superioty in weaponry over countries like NK and PK and India etc who have nukes. If those countries don't follow our example threaten them with superior conventional weaponry if they are that dangerous. I bet even the Chinese wopuld be happier if that whole region had no nukes.
Now as for Lazs Comment about us feeling safe during the cold war because of the US nukes stationed here. We didn't feel safe we felt like we'd been made a target. And many many people wanted the bloody things off our little Island.
