Why did we fight in Iraq?

Hundreds of raucous supporters celebrated the return of firebrand Iraqi cleric Muqtada al-Sadr on Thursday after his emergence from four years of exile in Iran, drawing a plea from him to show more discipline and restraint.

The populist whose militiamen once battled American and Iraqi forces left Iraq in 2007. Then, he was seen as a powerful but unpredictable leader of a street-fighting organization. Upon his return Wednesday, he was a legitimate political figure heading an organized movement that is a key partner in Prime Minister Nouri al-Maliki's new government.

In other words, when we withdraw, we will turn Iraq over to a government which includes the enemy we fought and who killed hundreds of U.S. soldiers in Sadr City.
