Inter‐American Treaty of Reciprocal Assistance
In practice, the treaty has been largely invoked, in conjunction with the consultative organs of the Organization of the American States (1948), to resolve intrahemispheric controversies, such as the dispute between Costa Rica and Nicaragua in 1955 or the Dominican Republic's attack on Venezuelan president Rómulo Betancourt in 1960. President John F. Kennedy did cite the Rio Treaty in justifying his quarantine order during the Cuban Missile Crisis of 1962. But usually when the United States decided that the Soviet Union threatened its hemispheric interests, Washington bypassed the treaty and acted unilaterally, as in Guatemala (1954), Cuba (1961), the Dominican Republic (1965), Chile (1970–73), and Nicaragua (1980s). The United States also refused the request of Latin American nations to invoke the Rio Treaty against Great Britain during the 1982 Anglo‐Argentine war over the Falkland Islands.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
Rio Treaty (Inter-American Treaty of Reciprocal Assistance), signed Sept. 2, 1947, and originally ratified by all 21 American republics. Under the treaty, an armed attack or threat of aggression against a signatory nation, whether by a member nation or by some other power, will be considered an attack against all (see Pan-Americanism). The treaty provides that no member can use force without the unanimous consent of the other signatories, but that other measures against aggressors may be approved by a two-thirds majority. It differs from previous inter-American treaties in that it is a regional treaty within a larger international organization; it recognizes the higher authority of the Security Council of the United Nations.
