Seol Kyung-chul's father fought alongside U.S. troops during the Korean War and had his life saved by American Marines. Decades later and in his father's memory, the renowned artist is giving back to family and his nation's decades-long ally—all through a gigantic work of art that has found a unique resting spot in Washington D.C. On May 13, the Pentagon unveiled Alliance 70—an 8.6-by-10.6-foot piece of contemporary art created by Kyung-Chul and composed of 300,000 tiny images that form the South Korean Taeguk symbol—during the 28th Korean Integrated Defense Dialogue. The artwork is the first to be donated by a partner-nation artist to hang in the Pentagon, according to the artist's son, Jason Seol, deputy chief of future operations at First Army Headquarters at Rock Island Arsenal, Ill. The artwork represents the seven-decade-long alliance between the United States and the Republic of Korea, symbolizing an enduring partnership and shared sacrifices. Specifically, it commemorates the 70th anniversary of the Mutual Defense Treaty between both nations that was signed Oct. 1, 1953, in Washington D.C. and just two months after the signing of the Korean Armistice Agreement. That treaty ensures that both countries provide mutual aid in the event of an armed attack, and permits the U.S. to station military forces in South Korea.
