North Korea Testing the Nuclear Bomb

One thing is, south korea has it's capital on the border with north korea. Isn't it about time they moved it? I mean it would they would be less vulnerable to an potential attack from North Korea if they did.

Second, if they are hoping North korea is going to collapse from within then they got to stop funding them. Personally, I think that the moment they said they were cheating on the treaty we should have cut off all aid. Talk is cheap afterall.
