This briefing book provides the only material needed to participate in the 1989 Great Decisions national non-partisan program of volunteer run discussions on U.S. foreign policy issues for classrooms and community groups. Everyone who participates in the program is invited to fill out the opinion ballots provided in the back of the book; the ballots are then tabulated and presented to various members of the U.S. Government and the national media. The topics for 1989 are: (1) "Ethics in International Relations: Power and Morality"; (2) "The Persian Gulf: Reassessing the U.S. Role"; (3) Latin American Debt: Living on Borrowed Time?"; (4) "Arms Agreements: Too Little Too Late, or Too Much Too Soon?"; (5) "China: Redefining the Revolution"; (6) "Farmers, Food and the Global Supermarket"; (7) "Horn of Africa: Empty Cornucopia?"; (8) "International Drug Traffic: An Unwinnable War?". Each topic area is discussed in considerable detail, with discussion questions and suggested readings at the end of each section. An index to Great Decisions topics (1980-1988), a profile of opinion ballot participants, and the 1988 ballot highlights are included, as are numerous black and white photographs and other graphics.
