The key to the future of the United States relations with its sister republics in South and Central America may well be found in this exhaustive study of Chile-United States relationships. The South American nation's relatively small population belies the powerful influence it wields in all American Hemisphere councils. For more than a century a small and tightly-knit group of upper and middle social sectors, representing a fairly broad cross-section of functional interest groups, has controlled the country's destiny. From 1880 to 1933 the course they followed led to many abrasive diplomatic incidents with the great "Colossus of the North." By no means can the blame for these clashes be placed exclusively on Chile's doorstep. Yet, while the diplomatic tangle has been largely unraveled since 1933, the intervening years have served only to expose a far more serious and sensitive source of trouble between the two nations: the wide gulf that separates the governed and the governing in Chile. The two problems, as Professor Pike points out, are inextricably interwoven. It has been a case of a participating, privileged minority served by a nonparticipating, nonprivileged majority. But the difference today is that the formerly docile masses are growing restless. The United States has contributed significantly, even if indirectly to Chile's present social unrest.
