Despite American success in preventing the conquest of South Korea by communist North Korea, the Korean War of 1950-1953 did not satisfy Americans who expected the kind of total victory that they had experience in World War II. In that earlier, larger war, victory over Japan cam after two atomic bombs destroyed the cities of Hiroshima and Nagasaki. But in Korea five years later, the United States limited itself to conventional weapons. Even after Communist china entered the war, Americans put China off-limits to conventional bombing as well as nuclear bombing. Operating within these limit, the U.S. Air Force helped to repel two invasions of South Korea while securing control of the skies so decisively that other United National forces could fight without fear of air attack.

During World War I 370,000 African Americans laboured, fought, and died to make the world safe for a democracy that refused them equal citizenship at home. The irony was made more bitter as black troops struggled with the racist policies of the American military itself. The overwhelming majority were assigned to labour companies those selected for combat were under-trained, poorly equipped, ad commanded by white officers who insisted on black inferiority. Still, African Americans performed admirably under fire: the 369th Infantry regiment was in continuous combat loner than any other American unit, and was the first Allied regiment to cross the Rhine in the offensive against Germany. The Unknown Soldiers , the only full-scale examination of the subject, chronicles the rigid segregation the limited opportunities for advancement the inadequate training, food, medical attention, housing, and clothing the verbal harassment and physical abuse, including lynchings the ingratitude, unemployment, and unprecedented racial violence that greeted their return. The Unknown Soldiers is an unforgettable, searing study of those wartime experiences that forced African Americans to realize that equality and justice could never be earned in Jim Crow America, but only wrested from its strangling grip.
