I thought Iraq was a 'moderate' Arab nation. Hm? For all intents and purposes it would appear as though Iran and Iraq will be at each other's throats forever, huh? It looks that way to me.
Saddam Hussein came to power in 1979. He remained there until 2003.
The Iran - Iraq War began in 1980 after Saddam took Iraqi leadership.
The Iran-Iraq War, also called the First Persian Gulf War, or the Imposed War (جنگ تحمیلی) in Iran, was a war between the armed forces of Iraq and Iran lasting from September 1980 to August 1988. It was commonly referred to as the (Persian) Gulf War until the Iraq-Kuwait conflict (1990–91), which became known as the Second Persian Gulf War and later simply the Persian Gulf War.
The war began when Iraq invaded Iran on September 22, 1980 following a long history of border disputes. The conflict saw early successes by the Iraqis, but before long they were repulsed and the conflict stabilized into a long war of attrition. The United Nations Security Council called upon both parties to end the conflict on multiple occasions, but a ceasefire was not agreed to until August 20, 1988, and the last prisoners of war were not exchanged until 2003. The war irrevocably altered politics in the area, playing into wider global politics and leading to the 1990 Iraqi invasion of Kuwait.
