After a period of contraction in the mid-1990s, U.N. peacekeeping operations (PKOS) have increased in number since 1999, putting pressure on major powers to contribute to new rescue and rehabilitation efforts around the globe. Yet it is not clear that the U.N.'s capability to carry out these operations effectively has increased -- particularly in Africa, where the major powers perceive few vital interests and are reluctant to contribute resources. In this updated edition of a 1999 study, a former U.S. ambassador to Mozambique draws lessons for today by taking a hard-nosed look at PKOS in Angola and Mozambique a decade ago. Extrapolating from these cases, Jett contends that PKOS can suffer from both inadequate resources and the U.N.'s organizational culture, which often hinders competent analysis and makes it difficult to appoint effective personnel in politically difficult situations. A pessimistic critique of peacekeeping, past and future.
