How can the coalition and the new Iraqi government best rein in tribal power? There is no alternative to military action in cases of hard-core resistance, such as Fallujah. Yet it should be possible to control most local tribal challenges as the old regime usually did, simply by effective policing and nonviolent displays of force (although the regime also employed extreme violence to put down political opposition). Nevertheless, the most potent vehicle for central government control is the distribution of government services and other benefits. The Iraqi countryside desperately needs new infrastructure, as well as many basic services and goods, such as purified water, treated sewage, roads, electricity, schools, hospitals, agricultural machinery, fertilizers, irrigation systems, and even high-quality seeds. Within a few months the central government in Baghdad, whether it is still largely run by the coalition forces or by Iraqis, should be able to provide all this and more—even to the most remote villages. At that point, tribal shaykhs will have to work with the government or risk being overthrown by their own people.
As we constantly state on this blog, if you understand the culture the strategy writes itself. You can read the full article, "The Iraqi Tribes and the Post-Saddam System" here.
