Moreover, under the Lee administration, scenarios involving the sudden collapse of North Korea and admission to the South were used as the basis for policy toward the North. This violated Article 1 of the South-North Basic Agreement and was nothing less than a rejection of the peace regime on the Korean Peninsula. Even if North Korea`s political regime were to collapse, the right decision would be for the United Nations to conduct a humanitarian intervention or send peacekeepers. The combined use of South Korean and U.S. forces to stabilize North Korean territory could constitute an invasion or occupation under international law. Moreover, America`s failure to stabilize Iraq and Afghanistan underscores the fundamental limits of such military intervention.
