comment explained a bit more :

While Americans are shelling out record prices for fuel, Iraqis pay only about 5 cents a gallon for gasoline - a benefit of hundreds of millions of dollars subsidies bankrolled by American taxpayers.

Although Iraq is a major petroleum producer, the country has little capacity to refine its own gasoline. So the U.S. government pays about $1.50 a gallon to buy fuel in neighboring countries and deliver it to Iraqi stations. A three-month supply costs American taxpayers more than $500 million, not including the cost of military escorts to fend off attacks by Iraqi insurgents.
