On August 4, 1950, the Eighth Army of United States of America began establishing a defensive line on the Naktong River in the Korean War. North Korean tyrant Kim Il-Sung had attacked the South in June, and by early August his forces had conquered most of South Korea, except for a small area in southeast Korea, near the port of Pusan. The defensive line, only fifty miles from the southern coast, was known as the Pusan Perimeter. Over the next six weeks, the U.S. Army and Marines halted intense North Korean offensives, saving the South from conquest. The defenders of Pusan set the stage for the next phase of the Korean War, General MacArthur’s brilliant amphibious landing at Inchon on September 15, which began the liberation of South Korea. Today, a Stalinist monarchy continues to oppress North Korea and to threaten war against the South. As Kim Jong-Il makes nuclear threats against the United States, and develops ICBMs, the necessity of removing his family’s kleptocratic tyranny is even clearer. Full-speed development of missile defense, and regime change in North Korea must be the foundations of American policy.
