HONOLULU — The inauguration Monday of Lee Myung Bak as the Republic of Korea's new president will open the door for a revitalization of the ROK-U.S. alliance, a relationship that has been severely tested and strained in recent years as a result of policy differences and more fundamental "vision" differences between Washington and Seoul.

An increasingly pragmatic approach toward the Korean Peninsula on the part of Washington and the advent of a more conservative, pro-alliance government in Seoul makes improved relations more likely and perhaps even somewhat easier to achieve, but by no means assured. If the alliance relationship is to be truly revitalized, both sides need to take some decisive steps, sooner rather than later.

President-elect Lee has already said he plans to place increased importance on alliance maintenance and that he understands the centrality of the alliance relationship to Korean Peninsula security. But what is missing, in both Seoul and Washington, has been a clear articulation of the continued rationale and vision for the alliance both today and after eventual North-South reconciliation or reunification. Such a vision existed, and was clearly articulated during the Kim Dae Jung and Clinton administrations, but has not really been spelled out since then.
