Historical Background
Tensions between Iran and Iraq existed before 1980. A central issue was the Shatt al-Arab waterway. This waterway is a channel for oil exports. It forms part of the border between the two nations. Both countries claimed sovereignty over parts of this route.
In 1975 the Algiers Agreement temporarily eased tensions. It adjusted border terms. However mistrust remained.

Iraqs president, Saddam Hussein feared that Irans revolution could inspire Iraqs majority population to rise against his Sunni-led government. Saddam also saw Iran as weakened by political purges and military restructuring after the revolution. Saddam believed the moment was strategically favorable. Iraq prepared for war.
