In its zeal to withdraw all U.S. troops in time for President Obama’s reelection campaign in 2012, the administration threw its weight behind then-Prime Minister Nouri al-Maliki, with disastrous consequences. Mr. Maliki’s Shiite sectarianism fractured the fragile political system and opened the way for the Islamic State.
In 2014, having pushed for Mr. Maliki’s removal, the administration bet on Haider al-Abadi; now, in its impatience to reduce the Islamic State before Mr. Obama leaves office, it clings to a prime minister who has proved unable to govern the country or reconcile its warring factions.
Mr. Abadi’s impotence was revealed most dramatically over the weekend, when Shiite supporters of anti-American firebrand Moqtada al-Sadr stormed into Baghdad’s walled-off Green Zone and invaded the parliament.
