The number of military contractors in Afghanistan rose to almost 74,000 by June 30, far outnumbering the roughly 58,000 U.S. soldiers on the ground at that point. As the military force in Afghanistan grows further, to a planned 68,000 by the end of the year, the Defense Department expects the ranks of contractors to increase more.
The Obama administration has sought to reduce its reliance on military contractors, worried that the Pentagon was ceding too much power to outside companies, failing to rein in costs and not achieving desired results.
Given the muscularity of Obama's foreign policy, one has to wonder if a time will come, in order to continue to support these wars without end, if there will be a reinstitution of the draft.
Given the current geopolitical situation, I wouldn't bet against it.
