On any given day, U.S. military forces are conducting joint naval patrols, training and equipping partners’ military forces, and providing humanitarian assistance. Non-warfighting programs like these increasingly constitute the main line of efforts for US military commands. In 2009, for example, about 150 countries received some form of U.S. military assistance. The programs are driven by an expansive view of U.S. security interests, demands made by many countries who seek to reduce their own security deficits, but also genuine U.S. interests.
