North Korea is a soverign nation. It doesn't need to listen to the US President. Obama has absolutely no power in North Korea except what they give him..... North Korea is not a signatory to the UN non-Proliferation Treaty (1) therefore can build or test nuclear weapons without it being 'illegal' under the treaty.
There is nothing the UN can do to stop them either. I think the only time North Korea will do what the rest of the world wants, is when its what North Korea wants too :(.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
