Worst debate thread ever.
Its hard to say, because N. Korea never agreed to the that non-nuclear weapon prolification treaty and the government are communist. I don't think there is right or wrong, countries like China, S. Korea, Japan plus others like the US are just scare that they will use it against them. These kinds of weapons should not be produced and it is really how a country use their nuclear capabilities and N. Korea isn't always the friendiest countries around to have such capabilities.
Another example is Iran, they say that the US are lying about them having nukes, but judging from the facts that kicking out UN inspectors and not allowing them going into some areas will create suspicion. I think Iran does and are creating nukes.
So all in all, weapons of mass destruction should not be created, because humans should always settle things with a simple fist fight - the good old days.
