The Clinton Administration has developed and applied a fairly detailed set of guidelines on the use of force. The Clinton criteria are derived in large measure from official military doctrine promulgated by Gen. Colin Powell, but they have been modified particularly in light of U.S. experience in Somalia. The current consensus doctrine calls for overwhelming force in defense of vital national interests in order to achieve a quick, decisive victory with low U.S. casualties. When important but not vital interests are involved, and costs and risks are commensurate with those interests, limited military means may be used for limited political objectives. In all cases, military operations should have clearly defined and achievable missions, with measurable milestones and an exit strategy to guard against mission creep. Public and congressional support is deemed advisable but not necessary. This article illustrates the application of this doctrine in Somalia, Haiti, and Bosnia.
