[Excerpt] The cessation of hostilities, or at least the abatement of widespread armed conflict, provides an opportunity for war-torn peoples and countries to rebuild their societies, economies and policies. Nations emerging from conflict face an immense challenge in making this transition. Ex-combatants must shift into newly formed national militaries or be reintegrated into civilian life. Nations such as Ethiopia, Liberia, Eritrea, Angola, Mozambique, Sierra Leone, Zimbabwe and others, have required highly effective programs for demobilization and reintegration, not only as part of the transition towards peace, but also to ensure that peace agreements bring stability and tranquility.
