Finally, Phillips suggests that oil has been the driving force in U.S. foreign policy for nearly thirty years. He suggests that the U.S. military has been transformed into a worldwide oil protection force. He suggests that various military events in the 1980s, as well as the 1991 Gulf War and the 2003 Invasion of Iraq, were primarily oil driven. Phillips makes a point that with Iraq at war for the past 25 years, and thus Iraqi oil production depressed for that time period, that most of Iraq's oil is still in the ground.
