direct U.S. military participation in The Vietnam War, the nation's 
            
 longest, cost fifty-eight thousand American lives. Only the Civil War 
            
 and the two world wars were deadlier for Americans. During the decade 
            
 of Vietnam beginning in 1964, the U.S Treasury spent over $140 billion 
            
 on the war, enough money to fund urban renewal projects in every major 
            
 American city. Despite these enormous costs and their accompanying 
            
 public and private trauma for the American people, the United States 
            
 failed, for the  first time in its history, to achieve its stated war 
            
 aims. The goal was to preserve a separate, independent, noncommunist 
            
 government in South Vietnam, but after April 1975, the communist 
            
 Democratic Republic of Vietnam (DRV) ruled the entire nation.
            
  The initial reasons for U.S. involvement in Vietnam seemed logical and 
            
 compelling to American leaders. Following its success in World War II, 
            
 the United States faced the future with a sense of moral rectitude and 
            
 material confidence. From Washington's perspective, the principal 
            
 threat to U.S. security and world peace was monolithic, dictatorial 
            
 communism emanating from he Soviet Union. Any communist anywhere, at 
            
 home or abroad, was, by definition, and enemy of the United States. 
            
 Drawing an analogy with the unsuccessful appeasement of fascist 
            
 dictators before World War II, the Truman administration believed that 
            
 any sign of communist aggression must be met quickly and forcefully by 
            
 the United States and its allies. This reactive policy was known as 
            
  In Vietnam the target of containment was Ho Chi Minh and the Vietminh 
            
 front he had created in 1941. Ho and his chief lieutenants were 
            
 communists with long-standing connections to the Soviet Union. They 
            
 were also ardent Vietnamese nationalists who fought  first to rid their 
            
 country of the Japanese and then, after 1945, to prevent France from 
            
 reestablishing its form...
