Give two reasons for the war that broke out in 1980 between ran and iraq

1. Saddam Hussein, the leader of Iraq, was afraid the Shiite south of Iraq (rich in oil) would rebel against the Sunni Baath Party, which Hussein headed, because of the 1979 Islamic Revolution in Iran.

2. The Shatt al-Arab waterway was also another reason. The waterway caused much tension in the region because who controlled it had much influence in trade for the region.
