This article advocates adapting the joint force to the emerging security strategy and security environment by enhancing the military’s shaping capabilities. Drawing on a dynamic equilibrium metaphor, the article considers several simultaneous stimuli that warrant adaptation of the force and a shift in focus to shaping capabilities. Central among them is the U.S. national security strategy shift from deterrence and containment to cooperation and engagement. It is important that military shaping capabilities be resourced in support of this strategy to prepare the Joint Force to take advantage of opportunities to protect and advance U.S. interests short of war, as well as confront aggression anywhere in the world at the outbreak of hostilities.
