A freeze is just the initial move in what needs to be a long-term strategy that changes underlying dynamics and addresses what each side sees as the core of the problem. We cannot really know what Kim wants, and what he might give up to get it, until we initiate dialogue. But since he took power, there have been strong signals that his ambitions go beyond a nuclear deterrent, that his real goal is economic development. Rather than threaten war or deepen sanctions, a more productive path is to nudge Kim down the same road that the major countries in East Asia have all taken: a shift from power to wealth. If Kim wants to be North Korea's developmental dictator, the United States' best long-term strategy is to help him do so. We cannot rationally expect him to surrender his nuclear deterrent at the beginning of that process, but it is the only realistic path for getting him to do so eventually.
