Who's really running Iraq?

The ability of America to make unilateral decisions in Iraq is diminishing by the month, but the White House was still horrified to hear the Iraqi prime minister Nouri al-Maliki appearing to endorse Barack Obama’s plan for the withdrawal of American combat troops over 16 months. This cut the ground from under the feet of John McCain who has repeatedly declared that ‘victory’ is at last within America’s grasp because of the great achievements of ‘the Surge’, the American reinforcements sent to Iraq in 2007 to regain control of Baghdad.

The success of ‘the Surge’ is becoming almost received wisdom in the US. This is strange since, if the US strategy did win such an important victory, why do America generals need more soldiers, currently 147,000 of them, in Iraq than they did before ‘the Surge’ started?
