Members of the neoconservative movement are also leaders of many influential "letterhead organizations" (LHO's) and think-tanks such as the American Enterprise Institute, Project for the New American Century, Committee for Peace and Security in the Gulf, Committee for the Liberation of Iraq, and the U.S. Committee for a Free Lebanon. These organizations act as a support system for many neoconservative beliefs and help members of the movement draft policy papers, raise money and media attention, and lobby policymakers in order to protect their own political and personal agendas. A sociologist who examined the memberships of such neoconservative organizations ultimately concluded that "the activities of fourteen organizations were coordinated by individuals who comprised a web of interlocking memberships."
