Is Nouri al-Maliki the Right Guy?

According to a recent AP report about discussion between President Bush and Iraqi Prime Minister Nouri al-Maliki, "The Iraqi prime minister owes his still-tenuous political survival in large part to staunch White House support, and Bush, even if dissatisfied with al-Maliki's leadership in some areas, recognizes there is virtually no alternative to replace him."

Given the lack of political progress that al-Maliki has made and that fact that there is no one in Iraq who shares his political platform close enough to replace him, wouldn't that indicate that we are supporting the wrong guy?
