This book analyses the foreign policy of the United States towards Cambodia by examining the belief system of the key players. It covers the invasion of Cambodia by the Vietnamese during the Carter administration, their occupation of Cambodia through both Reagan administrations and their eventual withdrawal during Bush''s tenure. It concludes on the brink of the UN sponsored elections of 1993 and provides a short epilogue which brings the story up to 1997. As an examination of US foreign policy within decision-making elites it makes a contribution to decision-making theory and foreign policy analysis as well as providing insights into regional politics.
