Nelson Aldrich Rockefeller (July 8, 1908 - January 26, 1979) was an American businessman and politician who served as the 41st Vice President of the United States from 1974 to 1977, and previously as the 49th Governor of New York (1959-1973). He also served as Assistant Secretary of State for American Republic Affairs for Presidents Franklin D. Roosevelt and Harry S. Truman (1944-1945) as well as Under-Secretary of Health, Education and Welfare under Dwight D. Eisenhower (1953-1954). A member of the wealthy Rockefeller family, he was a noted art collector and served as administrator of Rockefeller Center in Manhattan, New York. Rockefeller was a Republican who was often considered to be liberal, progressive, or moderate.
Because the perception was that the Alliance for Progress was a failure, shortly after taking office, on February 17, 1969, President Richard Nixon commissioned a study to assess the state of Latin America. Nixon appointed his most powerful political rival, New York Governor Nelson Rockefeller to direct the study. The poor relationship between the two politicians suggested that Nixon would not be that interested in the results of the study. There was a lack of interest for the region in the late 1960s to early 1970s. In April and May 1969, at the request of President Nixon, Rockefeller and a team of 23 advisors visited 20 American republics during four trips to solicit opinions of U.S. inter-American policies and to determine the needs and conditions of each country. Most of the trips turned out to be an embarrassment. Among the recommendations in Rockefeller's report to the President were preferential trade agreements with Latin American countries, refinancing the region's foreign debt, and removing bureaucratic impediments that prevented the efficient use of U.S. aid. The Nixon administration did little to implement the report's recommendations. Rockefeller wrote in his report preface that, There is general frustration over the failure to achieve a more rapid improvement in standards of living. The United States, because of its identification with the failure of the Alliance for Progress to live up to expectations, is blamed. People in the countries concerned also used our visit as an opportunity to demonstrate their frustrations with the failure of their own governments to meet their needs...demonstrations that began over grievances were taken over and exacerbated by anti-US and subversive elements which sought to weaken the United States, and their own governments in the process. The major part of the Rockefeller report suggested a reduction of U.S. involvement, "we, in the United States, cannot determine the internal political structure of any other nation". Because there was little the United States should or could do toward changing the political atmosphere in other countries, there was no reason to attempt to use economic aid as a political tool. This was the justification to reduce economic aid in Latin America. The Rockefeller report called for some aid to continue, but the report recommended creating more effective aid programs.
