This report provides information and analysis for use by Members of Congress as they deliberate on the Japanese response to the Gulf crisis and, perhaps more important, what it may mean for future U.S.-Japanese relations. The first chapter briefly reviews Japanese government actions in response to the crisis, from August 1990 to February 1991. A second section examines in detail the various factors and constraints that affected Japanese policy. The final section offers conclusions and examines implications of the episode for future U.S.-Japanese relations. Published sources for the report are cited in footnotes.
