Book excerpt: Systematically examining the different methods that both policy makers and scholars have used to analyze policy making and events, this new edition uses each of these different methods to analyze specific case studies. It applies the various models to seven cases: the Soviet deployment of nuclear missiles to Cuba, the U.S. decision to bomb North Vietnam, Communist China's invitation to President Nixon to visit, Nixon's acceptance of the invitation, Iran's taking of American hostages, the Iran-Contra affair, and the Gulf war against Iraq. For professionals in the fields of policy making and international relations.
