As the Trump administration prepares for a second summit with North Korean leader Kim Jong Un, how can it move negotiations past their current state of stagnation?

North Korea insists that a peace declaration must precede disarmament steps, but in October U.S. negotiators reverted to framing the end of the war as an “end state” that will follow the “final, fully verified denuclearization of North Korea.”

While this hardline position is appealing to some in Washington, if neither side is willing to give an inch, another summit it is unlikely to break through the impasse.
