Petroleum production has been linked with conflict for many years, leading to thousands of deaths due to these wars/conflicts. Petroleum deposits are in hardly any countries around the world; mainly in Russia and some parts of the middle east. Conflicts may start when countries refuse to cut oil production in which other countries respond to such actions by increasing their production causing a trade war as experienced during the 2020 Russia–Saudi Arabia oil price war. Other conflicts start due to countries wanting petroleum resources or other reasons on oil resource territory experienced in the Iran–Iraq War.
