This newly updated edition of Walter LaFeber's widely praised study of the evolution of U.S.-Panama relations contains two new chapters on the events that have occurred in the last ten years. LaFeber offers particularly detailed examinations of the earlier attempt to oust Manuel Noriega and Noriega's role in aiding the Nicaraguan Contras, as well as invaluable background information for understanding the 1989 crises. It remains the essential source for anyone who wants a complete picture of the canal debate from Balboa to the present.
