The Vietnam War was one of the most painful periods in American History. Some questions to ponder for today and tomorrow: 1. What strategy did the United States adopt in Vietnam? 2. In what ways did the United States underestimate its adversaries and overestimate its own strengths? 3. Do you think a different strategy would have been more successful? 4. What would victory in Vietnam have required, or was victory not a realistic objective?

The Lessons of Vietnam After the end of Persian Gulf War in 1991, Colin Powell, then chairman of the Joint Chiefs of Staff, outlined his vision for efficient and decisive military action. His plan is now referred to as the Powell Doctrine. An earlier version of the Powell Doctrine was articulated by President Ronald Reagan's Defense Secretary, Casper Weinberger, in Weinberger argued that the United States should only commit troops to combat after six tests had been met:  1. Is A Vital U.S. Interest At Stake? Before the United States goes to war, there must a clear risk to national security  2. Will We Commit Sufficient Resources To Win? Force, when used, should be overwhelming and disproportionate to the force used by the enemy.  3. Are Our Objectives Clearly Defined? In Powell’s words: "We owe it to the men and women who go in harm's way to make sure that this is always the case and that their lives are not squandered for unclear purposes." In addition, there must be a clear exit strategy from the conflict in which the military is engaged.  4. Will We Sustain the Commitment? Is the government prepared to sustain the effort if things go wrong.  5. Is There A Reasonable Expectation that the Public and Congress Will Support the Operation? There must be strong support for the campaign by the general public.  6. Have we exhausted our other options? Military action should be used only as a last resort.
