United States Interventions | ReVista
In the slightly less than a hundred years from 1898 to 1994, the U.S. government has intervened successfully to change governments in Latin America a total of at least 41 times. That amounts to once every 28 months for an entire century (see table).
Direct intervention occurred in 17 of the 41 cases. These incidents involved the use of U.S. military forces, intelligence agents or local citizens employed by U.S. government agencies. In another 24 cases, the U.S. government played an indirect role. That is, local actors played the principal roles, but either would not have acted or would not have succeeded without encouragement from the U.S. government.
While direct interventions are easily identified and copiously documented, identifying indirect interventions requires an exercise in historical judgment. The list of 41 includes only cases where, in the author’s judgment, the incumbent government would likely have survived in the absence of U.S. hostility. The list ranges from obvious cases to close calls. An example of an obvious case is the decision, made in the Oval Office in January 1963, to incite the Guatemalan army to overthrow the (dubiously) elected government of Miguel Ydígoras Fuentes in order to prevent an open competitive election that might have been won by left-leaning former President Juan José Arévalo. A less obvious case is that of the Chilean military coup against the government of President Salvador Allende on September 11, 1973. The Allende government had plenty of domestic opponents eager to see it deposed. It is included in this list because U.S. opposition to a coup (rather than encouragement) would most likely have enabled Allende to continue in office until new elections.
The 41 cases do not include incidents in which the United States sought to depose a Latin American government, but failed in the attempt. The most famous such case was the failed Bay of Pigs invasion of April 1961. Also absent from the list are numerous cases in which the U.S. government acted decisively to forestall a coup d’etat or otherwise protect an incumbent regime from being overthrown.
