Thanks to my favorite moderate and military historian, Fred Visel of Carl Sandburg College, who first asked me, “do you know you reversed the percentages of Sunni and Shia in Iraq in your editorial?” Yikes, I meant to say “Sunni-led Iraq.” I apologize for this inexcusable proof-reading error. Having made this error in public, I now cannot run for president.
Let me review, while Shia Islam makes up only 10-20 percent of the world’s Muslim population, Iraq has a Shia majority (between 60-65 percent), but had a Sunni controlled government under Saddam Hussein and cronies from 1958-2003. Sunnis make up over 75 percent of the world’s Muslim population. Islam is the world’s second largest religious community at about 23 percent of the total, with Christianity remaining the largest at about 33 percent of the total. Sunni and Shia, are two branches of Islam that disagree, sometimes violently, over religious doctrine and over who can be divinely ordained religious leaders. Finally, in Iran, which is largely Persian rather than Arab, 89 percent of the population is Shia and about 9 percent is Sunni. (If you like government figures, see the CIA World Factbook.)
Why, you may ask, does this religious split matter in relations between Iraq, Iran, the United States and stability in the larger Middle East? While Fred Visel rightly worries about the negative consequences of U.S. military actions in the region, I worry about an aggressive and terrorism-sponsoring Iran that gains influence as the United States gives the appearance of weakness in the nature of its withdrawal from Iraq. Iran may gain influence with its fellow Shia in Iraq as Iraq struggles to maintain its independence in the face of rival internal religious factions and in face of continued Iranian intervention in its internal affairs.
Expanding Iranian influence is not inevitable. While the population in Iran and Iraq are largely Shia, there is a long history of cultural and political animosity between Persian Iran and Arab Iraq; they have territorial and oil production disputes, and, in 1980, they began a bloody war. Iraq (under Saddam) used poison gas against Iranians and launched Scud missiles and bombers against Iran’s capital, Tehran. Iran retaliated against Baghdad. Casualty estimates are 1 million killed, 1 million or more wounded, with millions of refugees. The war ended in stalemate in 1988.
Currently, Iran wants to take advantage of a revitalized and empowered (by the U.S. overthrow of Saddam) Shia majority in Iraq. Iran has ties with the larger Shia parties and factions and with key military officers. On the other hand, many Shia Iraqi clergy (and most Sunnis and Kurds) do not share the vision of Iran’s “Islamic Revolution” or of a Supreme Religious Ayatollah running a country (i.e., a theocracy with a religious leader). A second disadvantage for Iran is the bitter aftertaste of Iran’s covert terrorism and economic activities in Iraq since 2003 that created additional conflicts with some religious and ethnic factions in Iraq.
How well Iran uses its leverage and advantages and minimizes Iraqi disaffection, depends not only on Iraqi politics, but also the image of American strength (or weakness) in the region and how well the United States deals with the current Iranian regime.
