Restructuring the US-South Korea alliance to deal with the second Korean nuclear crisis

As the US-South Korea alliance faces the second Korean nuclear crisis, Seoul and Washington no longer share a common unifying threat perception of North Korea. This divide has allowed North Korea to advance its interests by playing a 'South Korea card' against the United States in the nuclear standoff. The divide is not a transient problem that can be ignored or addressed with ad hoc fixes but a secular phenomenon rooted in South Korea's growing wealth and deepening democracy. What is needed now is more distance in the alliance. The alliance must be restructured to reflect the reality that South Korea can defend itself against North Korea without the help of the United States. For both Seoul and Washington, the restructured alliance would produce a more complete and robust set of options to advance their respective North Korea policies.
