Exit strategy
An exit strategy is a means of leaving one's current situation, either after a predetermined objective has been achieved, or as a strategy to mitigate failure. An organisation or individual without an exit strategy may be in a quagmire. At worst, an exit strategy will save face; at best, an exit strategy will peg a withdrawal to the achievement of an objective worth more than the cost of continued involvement.
In warfare
In military strategy, an exit strategy is understood to minimise losses of what military jargon called "blood and treasure" (lives and material).
The term was used technically in internal Pentagon critiques of the Vietnam War (cf. President Richard Nixon's promise of Peace With Honor), but remained obscure to the general public until the Battle of Mogadishu, Somalia when the U.S. military involvement in that U.N. peacekeeping operation cost the lives of U.S. troops without a clear objective. Republican critics of President Bill Clinton derided him for having no exit strategy, although he had inherited an active military operation from his predecessor, President George H. W. Bush. The criticism was revived later against the U.S. involvement in the Yugoslav wars, including peacekeeping operations in Bosnia and Kosovo and the Kosovo war against Serbia.
