Andrew Krepinevich would like you to set up MemeStreams in Iraq. Can you work that into your schedule this week? The Iraqis would really appreciate it.

Because they lack a coherent strategy, U.S. forces in Iraq have failed to defeat the insurgency or improve security. Winning will require a new approach to counterinsurgency, one that focuses on providing security to Iraqis rather than hunting down insurgents. And it will take at least a decade.

It will require a good understanding of Iraqi tribal politics. In many areas of Iraq, the tribe and the extended family are the foundation of society, and they represent a sort of alternative to the government. There are roughly 150 tribes in Iraq of varying size and influence, and at least 75 percent of Iraqis are members of a tribe. Creating a coalition out of these groups would require systematically mapping tribal structures, loyalties, and blood feuds within and among tribal groups; identifying unresolved feuds; detecting the political inclinations of dominant tribes and their sources of power and legitimacy; and determining their ties to tribes in other countries, particularly in Iran, Syria, and Turkey.

Accurate tribal mapping could guide the formation of alliances between the new Iraqi government and certain tribes and families, improve the vetting of military recruits and civil servants, and enhance intelligence sources on the insurgency's organization and infrastructure.

On second thought, maybe we'll just use MySpace instead.
