Here’s a negotiating question: if you have a lot of leverage, why give everything away before you even get to the table?

I ask that question because of North Korea’s apparent willingness to surrender anything and everything without reciprocity from the U.S. On Thursday, South Korea’s president Moon Jae-in declared North Korean leader Kim Jong Un has now waived his previous demand he would denuclearize only if the U.S. were to withdraw its military forces from South Korea.
