The sheer size of the military establishment and the habit of equating spending on it with patriotism make both sound management and serious oversight of defense expenditures rare. As a democracy, we are on an unusual and risky path. For several decades, we have maintained an extraordinarily high level of defense spending with the support of both political parties and virtually all of the public. The annual debate about the next year’s military spending, underway now on Capitol Hill, no longer probes where real cuts might be made (as opposed to cuts in previously planned growth) but only asks how big the increase should be.
