The concept of the “tribe” has captured the imagination of military planners, who have been inspired partly by social scientists. Interest in tribes stems from events in Iraq's al-Anbar province, where the US military has co-opted Sunni “tribal” leaders. Some social scientists have capitalized on these developments by doing contract work for the Pentagon. For example, the “Iraq tribal study”—prepared by a private company consisting of anthropologists and political scientists among others—suggests employing colonial-era techniques (such as divide and conquer) for social control. It also advocates bribing local leaders, a method that has become part of the US military's pacification strategy. Such imperial policing techniques are likely to aggravate armed conflict between and among ethnic groups and religious sects. Observers report that the US strategy is creating a dangerous situation resembling the Lebanese civil war, raising ethical questions about social scientists' involvement in these processes.
