The defense budget in 2010--$664 billion (not counting the Iraq and Afghanistan wars)--equalled that of the rest of the world combined. One dollar of every five spent by the U.S. Government was for defense. The amount spent represents 80% growth since 2000. Why? One reason: the big weapon systems oriented to fighting other empires (e.g., Russia and China). For example, $600 million for the littoral combat ship and $13 billion for amphibious landing vehicles (whose purpose has even been questioned by Sec. of Defense William Gates). It would seem that the military contractors--the military industrial complex, moreover--are firmly entrenched and in control.
