Early this month Admiral Mike Mullen, chairman of the U.S. Joint Chiefs of Staff, delivered what military experts are saying was the final nail in the coffin of  the Powell doctrine, a set of principles that General Colin Powell during his tenure as chairman laid out for the use of military force. A key element was that the military plan should employ decisive and overwhelming force in order to achieve a rapid result. A clear exit strategy must be thought through right from the beginning and the use of force must only be a last resort, Powell said, the experience of Vietnam clearly weighing on him.
