The major deficit in the U.S. balance of payments has long been military spending abroad. The entire payments deficit, beginning with the Korean War in 1950-51 and extending through the Vietnam War of the 1960s, was responsible for forcing the dollar off gold in 1971. The problem facing America’s military strategists was how to continue supporting the 800 U.S. military bases around the world and allied troop support without losing America’s financial leverage. The solution turned out to be to replace gold with U.S. Treasury securities (IOUs) as the basis of foreign central bank reserves. After 1971, foreign central banks had little option for what to do with their continuing dollar inflows except to recycle them to the U.S. economy by buying U.S. Treasury securities. The effect of U.S. foreign military spending thus did not undercut the dollar’s exchange rate, and did not even force the Treasury and Federal Reserve to raise interest rates to attract foreign exchange to offset the dollar outflows on military account. In fact, U.S. foreign military spending helped finance the domestic U.S. federal budget deficit.
