Several of today’s front pages feature iconic images of U.S. troops marching onto troop transports and into the sunset in Iraq. Today’s story by Ernesto Londoño in the Washington Post, features Lt. Col. Mark Bieger of the 4th Stryker Brigade, 2nd Infantry Division, “This is a historic mission!” Beiger bellows as his troops prepared to depart Baghdad for the last time, “A truly historic end to seven years of war.”

No disrespect to Col. Bieger and his troops, but the war isn’t over, and it won’t be so long as there are significant number of U.S. troops in Iraq at risk of being caught in the cross-fire of a sectarian civil war.

The Iraqi government, more than five months after nationwide elections, remains in limbo. Talks over a power sharing arrangement have broken down. Meanwhile, violence is on the rise. Call it whatever you like, but the 50,000 troops who remain in Iraq are still dealing with a lot of challenges.

Much of the confusion in the media reporting revolves around semantics, words and phrases such as “combat” and “combat units.” It doesn’t help that George W. Bush declared on May 1, 2003 that “major combat operations in Iraq have ended” under that infamous “Mission Accomplished” banner. But beyond Bush’s irrational exuberance, such terms are increasingly misleading in an era in which conventional, state vs. state organized violence — what we used to think of as war — has been replaced by murky, disorganized violence, perpetrated by disparate militias, or merely disgruntled individuals unhappy with their lot in life, and determined to take it out on anyone who happens to be around at the time.

Unfortunately, I have very little confidence that that state of affairs will change any time soon. And I seriously doubt that our people — our men and women in uniform, and, explains Michael Gordon in the New York Times, soon many more U.S. civilians and contractors — will be able to put everything right, and not for lack of trying. Meanwhile, I am deeply troubled by the rising chorus of voices calling on the Obama administration to ignore the remaining provisions of the status of forces agreement (SOFA) and prepare for an indefinite military presence in Iraq. (On this, see Ted Galen Carpenter’s latest entry at TNI’s The Skeptics blog.)

So, no, the war isn’t over. For better or worse (and chiefly the latter), Americans will remain associated with an unpopular and government in Baghdad as it struggles to hold together the country’s disparate factions. They will be at great risk if the current political paralysis collapses into still wider violence.

Needless to say, I hope that doesn’t happen. But I won’t be striking up the band and declaring the war American in Iraq to be truly over, until all of our troops are back home.
