Eighteen days of protests in Egypt in 2011 electrified the world. But more than twice that many days of protest in Iraq have gone almost unnoticed in the United States. Iraqi army troops killed five Sunni protesters in Fallujah on Jan. 25, after a month of anti-government protests in Anbar, Nineveh and Salahuddin provinces and elsewhere for which thousands turned out. Al-Qaeda in Iraq and Iranian-backed Shiite militias are re-mobilizing. Iraq teeters on the brink of renewed insurgency and, potentially, civil war.
