Washington: South Korean President Yoon Suk Yeol's unexpected declaration of martial law has placed the United States in an awkward position, prompting swift reassurances from U.S. officials about the strength of the alliance with South Korea. The U.S. has emphasized its commitment to an "ironclad" partnership and expressed hopes for a "peaceful" resolution to the situation. According to Yonhap News Agency, the declaration of emergency martial law was made by President Yoon on Tuesday night, causing immediate concern in Washington. Deputy Secretary of State Kurt Campbell stated that the U.S. was observing the situation with "grave concern," while a White House official highlighted serious worries on the part of the U.S. government. The timing of the crisis is significant as it comes at a moment when the administration of President Joe Biden has been celebrating the strengthening of the U.S.-South Korea alliance and enhanced trilateral cooperation with Japan, marking it as a key achievement of his term, whic h concludes next month. Following the South Korean Cabinet's decision to revoke martial law, a spokesperson for the U.S. National Security Council (NSC) expressed relief but reiterated the crucial role democracy plays in the U.S.-South Korea relationship. "Democracy is at the foundation of the U.S.-ROK alliance, and we will continue to monitor the situation," the official stated, emphasizing the potential risks martial law posed to South Korea's democratic processes. The U.S. response included both concern and commitment to the alliance, highlighting the importance of resolving any "political" disagreements in South Korea peacefully. Vedant Patel, principal deputy spokesperson for the State Department, reinforced this stance, stating, "Our alliance with the Republic of Korea is ironclad, and we're fully committed to that." Patel declined to comment on whether the martial law declaration was political, instead focusing on the U.S.'s efforts to understand the situation and respond appropriately to any develo pments that might affect U.S. personnel and citizens in South Korea. At the Pentagon, the martial law issue was also a focal point, with Pentagon press secretary Maj. Gen. Pat Ryder confirming that there had been no changes in the U.S. Forces Korea's posture following the declaration. "We're closely monitoring the situation, but I'm not aware of any force posture changes," he said. President Yoon's martial law declaration was based on accusations against the nation's opposition of hindering government operations with "anti-state" activities. However, the declaration was short-lived, as his Cabinet convened roughly six hours later to rescind it.
