Article: Whenever the United States has asked this question — as it did with China in the 1950s or Vietnam in the 1970s — the most important point to remember is: The local rulers did. The Chinese nationalists and the South Vietnamese government were corrupt, inefficient and weak, unable to be inclusive and unwilling to fight with the dedication of their opponents. The same story is true of Iraq, only much more so. The first answer to the question is: Prime Minister Nouri al-Maliki lost Iraq. The prime minister and his ruling party have behaved like thugs, excluding the Sunnis from power, using the army, police forces and militias to terrorize their opponents. The insurgency the Maliki government faces today was utterly predictable because, in fact, it happened before. From 2003 onward, Iraq faced a Sunni insurgency that was finally tamped down by Gen. David Petraeus, who said explicitly at the time that the core element of his strategy was political, bringing Sunni tribes and militias into the fold. The surge’s success, he often noted, bought time for a real power-sharing deal in Iraq that would bring the Sunnis into the structure of the government.
