U.S. bases and troops abroad cost about $170 billion in 2012

Evidence

With those additions, my estimate of war zone costs for 2012—including appropriations for military construction and maintenance, troop salaries, and so on—was 97 billion. My estimate for the total costs to maintain U.S. bases and troops around the globe—both within war zones and outside them—thus reached some 170 billion for fiscal year 2012. — David Vine, Base Nation_ How U.S. Military Bases…, 647
