Ok, thinking about it, on principle I agree that not every country should have nuclear weapons. I'm sure everyone else thinks the same. And yes, it's probably sensible that a superpower e.g. or rather i.e. the US has them for world defence.
The problem is that the US then see themselves as having the right to go storming into every country that might possibly have wmd's. Hmmm.
Frankly, after Iraq, the US has very little credbility in my eyes regarding international relations. Because I believe that something needed to be done, but I don't support how they did it and I certainly don't support the mess that Iraq is in now.
