Following the collapse of Soviet power, America’s leaders set more ambitious goals for the U.S. military, despite its smaller size. This entailed requiring the armed services to sustain and extend their continuous global presence, improving their readiness and speed, increasing peacetime engagement activities, and preparing to conduct more types of missions quickly and in more areas. Recent U.S. strategy has looked beyond the traditional goals of defense and deterrence, seeking to use military power to actually prevent the emergence of threats and to “shape” the international environment. U.S. defense planners also elevated the importance of lesser and hypothetical threats, thus requiring the military to prepare for many more lower-probability contingencies.
