Oil war

An oil war is a conflict about petroleum resources, or their transportation, consumption, or regulation. The term may also refer generally to any conflict in a region that contains oil reserves or is geographically positioned in a location where an entity has or may wish to develop production or transportation infrastructure for petroleum products. It is also used to refer to any of a number of specific oil wars.
A 2016 study argued that oil wars were largely a myth. It argued that proponents of oil wars underestimate the ability to seize and exploit foreign oil fields, and thus exaggerate the value of oil wars. The study examined four cases commonly described as oil wars (Japan's attack on the Dutch East Indies in World War II, Iraq's invasion of Kuwait, the Iran-Iraq War, and the Chaco War between Bolivia and Paraguay), finding that control of additional oil resources was not the main cause of aggression in the conflicts.
On April 5, 2021, United States vice president Kamala Harris mentioned “For years there were wars fought over oil; in a short time there will be wars fought over water”, in a talk in Oakland to promote the American Jobs Plan.
