29 March Wall Street Journal commentary - How to Win in Iraq and How to Lose by Arthur Herman.

To the student of counterinsurgency warfare, the war in Iraq has reached a critical but dismally familiar stage.

On the one hand, events in that country have taken a more hopeful direction in recent months. Operations in the city of Najaf in January presaged a more effective burden-sharing between American and Iraqi troops than in the past. The opening moves of the so-called surge in Baghdad, involving increased American patrols and the steady addition of more than 21,000 ground troops, have begun to sweep Shiite militias from the streets, while their leader, Moqtada al-Sadr, has gone to ground. Above all, the appointment of Lt. Gen. David Petraeus, the author of the U.S. Army's latest counterinsurgency field manual, as commander of American ground forces in Iraq bespeaks the Pentagon's conviction that what we need to confront the Iraq insurgency is not more high-tech firepower but the time-tested methods of unconventional or "fourth generation" warfare...

There, French troops and a beleaguered local government faced an insurgency mounted by Muslim extremists who had managed to gain the upper hand. In response, the leadership of the French army had to figure out, almost from scratch, how to fight unconventional wars of this kind--with results that have influenced the thinking of counterinsurgency experts ever since...
