Kim Jong Un must go. It's time for a Korean democratic unification. - AEI
The Trump team must move toward a strategy of ultimate unification of the peninsula. There are many main reasons for this. First, the nuclear problem is really a regime problem. The Kim family has made its legacy synonymous with becoming a nuclear state that can ultimately unify the peninsula on its own terms. Second, it is unclear whether long-term deterrence is stable. Northeast Asia would have to become very militarized. The military postures of Japan, South Korea, and the United States would have to favor the offense to be ready to strike down missiles and to keep Kim on the defensive. And it is unclear whether Japan and South Korea would remain non-nuclear. The US should still seek to limit the proliferation of nuclear weapons.
