Iraq is really three separate geographical regions, now contested by Kurds and Arabs ethnically, Arabic and Kurdish speakers linguistically, and Sunni and Shiite Muslims religiously. Ethnically Iraqis are approximately 75 percent Arabs, 20 percent Kurds, and 5 percent Turkmen and Assyrians. Religiously they are 65 percent Shiite Muslims, 30 percent Sunni Muslims, and 5 percent Christians and Mandeans. Monarchs and dictators held the tripartite configuration together for nine decades as modern Iraq. Without their iron fists enforcing coexistence, bloody fault lines are sundering the artificial nation back into its customary divisions.
