About giving up nuclear weapons:
The North\’s Rodong Sinmun newspaper rejected as groundless and unacceptable the US and South Korean condition that it agree to dismantle its nuclear weapons and suspend missile launches.
\”If the DPRK sits at a table with the US it has to be a dialogue between nuclear weapons states, not one side forcing the other to dismantle nuclear weapons,\” the newspaper said, referring to the North by its official name, the Democratic People\’s Republic of Korea.
The point being that it has never signed the non-proliferation treaty thus is not bound by its provisions. Iran has and therefore is. But it\’s a fairly basic idea in international law that a State is not bound by treaties that it hasn\’t signed.
