Kagan argues that the U.S should hold Iraq responsible for continuing free elections and democratic process after the American withdrawal, and efforts to prevent sectarian strife and promote reconciliation between the different religious groups and factions. He cites Iraq's lack of aircraft to maintain air sovereignty, and the challenges facing Iraq in preventing use of its territory by terrorist groups and countering Iranian influence. Similiar concerns are expressed by Lt. Gen. Frank Helmick, deputy commander of U.S. forces in Iraq.
