Debt: The First 5,000 Years

by David Graeber

The U.S. military, unlike any other, maintains a doctrine of global power projection: that it should have the ability, through roughly 800 overseas military bases, to intervene with deadly force absolutely anywhere on the planet. In a way, though, land forces are secondary; at least since World War II, the key to U.S. military doctrine has always been a reliance on air power. The United States has fought no war in which it did not control the skies, and it has relied on aerial bombardment far more systematically than any other military—in its recent occupation of Iraq, for instance, even going so far as to bomb residential neighborhoods of cities ostensibly under its own control.
