Well, the Korean War ended in a stalemate; the Vietnam War we just got tired of fighting and went home; Panama and Grenada were brief operations, not wars; Desert Storm was a bigger, but also brief, operation in which most of the enemy air force ran away instead of fighting; and we're still conducting counterinsurgency and counterterrorist operations in Afghanistan.
