Why did the American adviser accuse?

(9)A top American adviser on Iraq has accused the U.S. military of glossing over an upsurge in violence just months before its troops are due to be withdrawn. The U.S. Special Inspector General for Iraq Reconstruction, Stuart W Bowen Jr, said the killing of U.S. soldiers and senior Iraqi figures as well as attacks in Baghdad had all risen, making Iraq more dangerous than it was a year ago. Meanwhile, the Iraqi Prime Minister Nouri al-Maliki has announced his country will go ahead with a plan to buy 36 F-16 fighter jets from the United States.
    Iraq has blown hot and cold over a possible multibillion-dollar deal to buy F-16s from the U. S. The aim ostensibly is to protect Iraqi airspace and revive its enfeebled air force.(10)Iraq put the original deal on hold in order to use the funds to buy basic food stuffs instead, but Iraq’s offers have apparently been boosted by soaring oil prices since then. With U.S. troops due to withdraw shortly, Mr. Maliki has now revived the F-16 deal as part of Iraq’s efforts to show it’s moving towards military self-sufficiency.
