Paul Stares argues that multilateral security assurances might induce Pyongyang to agree to the dismantlement of North Korea’s nuclear program:

The diplomatic vehicle for such security assurances would be a United Nations-sponsored initiative to formally end the Korean War and dismantle the present armistice arrangements. As part of a peace treaty, the principal signatories — the United States, China and the two Koreas — would commit themselves to establishing normal diplomatic relations, recognizing the territorial integrity of both Koreas and, most important, ensuring a nuclear-free peninsula.

Complementary agreements involving conventional arms control, economic assistance, access to international financial institutions and humanitarian aid could also be discussed, but not as prerequisites for replacing the Korean armistice with a permanent peace settlement.

The argument is an op-ed in the New York Times, “To Ban the Bomb, Sign the Peace.”
