A special report of 38 North, co-authored with Carla Freeman and available at https://www.38north.org/wp-content/uploads/pdf/38-North-SR-1804_Freeman-Gurtov.pdf
From the report:
“Understanding what North Korea really wants is essential because
hope that progress toward denuclearization can be achieved through an engagement strategy rests on the idea that both sides share a common goal of improving mutual security. In this essay, we
argue that there is space for negotiation around the idea of mutual security, defusing tensions and creating conditions for eventual denuclearization throughout the Korean Peninsula.
We come at this discussion of engagement and what could be achieved by engaging North Korea today from two quite different perspectives on world affairs. One of us has spent decades
defining a human-interest approach to international affairs centered on incorporating global-citizen values in policymaking such as peace (minimization of violence and conflict resolution), mutual respect and social justice. The other sees engagement as creating opportunities for trust building and problem solving through diplomacy between states amid the international insecurity
endemic to international relations. The differences in how we see the potential for the behavior of states importantly do not preclude a shared definition of engagement and its importance in a diplomatic strategy for North Korea.”

Did you see the Einstein quote in The Atlantic”?
“I am not saying that the United States should not manufacture and stockpile the bomb, for I believe that it must do so; it must be able to deter another nation from making an atomic attack when it also has the bomb,” Einstein said. “To keep a stockpile of atomic bombs without promising not to initiate its use is exploiting the possession of bombs for political ends….Unless there is a determination not to use [atomic bombs] that is stronger than can be noted today among American political and military leaders, and on the part of the public itself, atomic warfare will be hard to avoid.”
Timely. Kim and Trump are playing lethally perilous politics.
