Many factors influence the relative success of nation-building activities, argues this RAND report, but the most important are levels of time, manpower, and money. The report analyzes the cases of U.S. involvement in Germany, Japan, Somalia, Haiti, Bosnia, and Kosovo, focusing on questions of security, humanitarian concerns, civil administration, democratization, and reconstruction. The report finds that multilateralism can be more complex, but is considerably less expensive and often results in more thoroughgoing change.
