But the tragedy continued. The Korean War, known as the "Forgotten War" in the United States was known militarily at the time as the "scorched-earth" policy, which was essentially a three-year fire-bombing campaign. Not only were more bombs dropped on Korea than on Europe during World War II, but also more napalm was used than during the Vietnam War. In Pyongyang, a city of 400,000 people in 1950, approximately 420,000 U.S. bombs were dropped—more than one per resident. At one point during the war, President Truman seriously considered dropping an atomic bomb on North Korea.
