What Im trying to say is attempting to prevent hostile countries around them gaining nuclear technology indefinitely isnt feasible. A better option is to address the reasons they are hostile.
But that might prevent hostilities from happening... haha
Maybe we look at the actions of nations, instead of their words. It is clear how much the nuclear powers respect 'playing by the rules', after all - half of them don't even bother with the NPT, except to waive it at Iran.
