Abstract

This article, the first in a series for The Diplomat by Dr. Clint Work, examines the transition of wartime operational control (OPCON) from the United States to the Republic of Korea (ROK), a long-debated and complex aspect of the U.S.-ROK alliance. Focusing on the “control rod” logic, which underscores U.S. leadership to deter North Korean aggression and moderate South Korean responses, the analysis explores historical and contemporary factors that have advanced, delayed, or complicated the transition. By tracing developments from post–World War II arrangements through the Korean War, Cold War command structures, and 21st-century strategic adjustments, the study highlights the persistent tensions between U.S. influence and South Korean autonomy, offering insight into alliance modernization and regional security dynamics.
