The war I witnessed for more than five years in Iraq is over. In July, there were five American fatalities in Iraq, the lowest since the war began in March 2003. In Mosul recently, I chatted with shopkeepers on the same corner where last January a Humvee was blown apart in front of me. In the Baghdad district of Ghazilia — where last January snipers controlled streets awash in human waste — I saw clean streets and soccer games. In Basra, the local British colonel was dining at a restaurant in the center of the bustling city.

For the first time in 15 trips across the country, I didn't hear one shot or a single blast from a roadside bomb. In Anbar Province, scene of the fiercest fighting during the war, the tribal sheiks insisted to Barack Obama on his recent visit that the U.S. Marines had to stay because they were the most trusted force.
