Memories and lessons from the war are still a major factor in American politics. One side views the war as a necessary part of the Containment policy, which allowed the enemy to choose the time and place of warfare. Others note the U.S. made major strategic gains as the Communists were defeated in Indonesia, and by 1972 both Moscow and Beijing were competing for American support, at the expense of their allies in Hanoi. Critics see the conflict as a "quagmire"—an endless waste of American blood and treasure in a conflict that did not concern US interests. Fears of another quagmire have been major factors in foreign policy debates ever since. The draft became extremely unpopular, and President Nixon ended it in 1973, forcing the military (the Army especially) to rely entirely upon volunteers. That raised the issue of how well the professional military reflected overall American society and values; the soldiers typically took the position that their service represented the highest and best American values.
