Although the threat of "resource wars" over possession of oil reserves is often exaggerated, the sum total of the political effects generated by the oil industry makes oil a leading cause of war. Between one-quarter and one-half of interstate wars since 1973 have been connected to one or more oil-related causal mechanisms. No other commodity has had such an impact on international security. The influence of oil on conflict is often poorly understood. In U.S. public debates about the 1991 and 2003 Iraq wars, both sides focused excessively on the question of whether the United States was fighting for possession of oil reserves; neither sought a broader understanding of how oil shaped the preconditions for war.
