There is an interesting article--"Oil for War"--in "The American Conservative"
http://amconmag.com/2008/2008_03_10/cover.html
"...In order to secure the third-richest country on the planet, the U.S. military is burning enormous quantities of petroleum. And nearly every drop of that fuel is imported into Iraq. These massive fuel requirements—just over 3 million gallons per day for Operation Iraqi Freedom, according to the Pentagon’s Defense Energy Support Center—are a key reason for the soaring cost of the war effort."
Oil for war is in direct competition with oil for agriculture.
