The North Atlantic Treaty Organization (NATO) was the most successful collective security arrangement among states in the 20^th century. Having deterred and outlasted its primary adversary, the Soviet Union, NATO now faces the challenge of redefining its roles and purposes in the 21^st century. Like all pluralist organizations, the Alliance must reflect the common interests of its 28 members, and defining common interests that motivate all members to sacrifice for the good of the whole has been difficult. In the absence of a direct common military threat, disparate interests, commitments, and visions of the transatlantic future have fragmented Alliance coherence.

The East African Standby Force (EASF) is East Africa's contribution to the African Union's African Standby Force, which is an international and continental military force with both a civilian and police component to be deployed in Africa during times of crisis. Although the EASF is still under development and in need of capacity-building assistance, the United States does not have the authorities to provide direct assistance to this regional force. Instead, Washington must rely on bilateral assistance mechanisms that are cumbersome and less efficient than dealing directly with the EASF.

Where do effective military and police institutions come from in a society that is not already based on the rule of law? In particular, can informal militias based on patron/client relations be successfully reformed or integrated into professional and effective state security institutions? We do not have good answers to these questions. Yet the United States and its allies are wrestling with them daily in many locations around the globe. My goal in this article is to examine what we do know about historical and recent situations that to some degree mirror these current challenges, and to draw out some unexpected practical suggestions about what might work on the ground.
