Excellent discussion of the OPCON transfer issue from Bruce Klinger. Needless to say I agree with these recommendations (but please read the entire essay).
Recommendations for an Effective Military Strategy
Before people get up in arms about a ROK General Officer in Command of the ROK/US Combined Forces Command because of the so-called "Pershing Rule," those critics need to understand the command relationships and if they do not then they need to hold their fire until they do. We need to understand that the ROK/US CFC answers to the Military Committee which as I have said over and over again is made up of representatives of and answers to the National Command and Military Authorities of Korea and and the National Authority of the Untied States. Here is an attempt to summarize of the command relationships:
The ROK/US Combined Forces Command (ROK/US) is the warfighting headquarters of the ROK/US Alliance. It answers to the Military Committee which provides strategic direction and operational guidance to the ROK/US CFC and consists of representatives of both nations' National Command and Military Authorities (NCMA) (ROK) and National Authority (NA) (US). The ROK Joint Chiefs of Staff (JCS) retains command of all ROK forces and when directed by the ROK NCMA provides forces to the ROK/US CFC for employment under its operational control. US Forces Korea (USFK) is a subunifed command of US Pacific Command (PACOM) which is the Combatant Command of the US and PACOM retains combatant command of all US forces in the Korean Theater of Operations with USFK exercising OPCON of US forces for PACOM. USFK provides forces to the ROK/US CFC for employment under its operational control when directed by US National Authority. The United Nations Command (UNC) is responsible for maintaining the Armistice and answers to the US JCS as the designated executive agent for the United Nations. The UNC may also have operational control of international forces from United Nations' sending states should sending states chose to provide forces for the defense of the ROK in accordance with UN Security Council Resolutions 82 through 85 (circa 1950).
