The central principle contained in its articles is that an attack against one is to be considered an attack against them all; this was known as the "hemispheric defense" doctrine. Despite this, several members have breached the treaty on multiple occasions.

The treaty was initially created in 1947 and came into force in 1948, in accordance with Article 22 of the treaty. The Bahamas was the most recent country to sign and ratify it in 1982.

Background

The United States maintained a hemispheric defense policy relative to European influence under the Monroe Doctrine from 1823 onwards, and became increasingly interventionist following the 1904 promulgation of the Roosevelt Corollary. During the 1930s the United States had been alarmed by Axis overtures suggesting military cooperation with Latin American governments; apparent strategic threats against the Panama Canal were of particular concern. These were discussed in a series of meetings of the International Conference of American States and at the 1936 Inter-American Conference for the Maintenance of Peace. During World War II Washington had been able to secure support for the Allies from all individual governments in the Americas except Uruguay (which remained neutral until 22 February 1945) and Argentina (which had difficult relations with the Allied powers from 1944 to 1945 but declared war on the Axis on 27 March 1945).^{[dead link]} Some countries had signed the Declaration by United Nations in early 1942 and more had signed by the end of 1945.

However, Latin American countries were largely sidelined from the Allied discussions of a postwar security order, held at Dumbarton Oaks from August to October 1944. The Brazilian Ambassador to Washington, Carlos Martins Pereira e Souza, "protested the violation of inter-American norms of consultation in the preparation of postwar plans." These protests led to a series of consultations as well as to a Mexican proposal for an inter-American meeting. At the Inter-American Conference on the Problems of War and Peace, at Chapultepec Castle in Mexico City during February and March 1945, discussions of the post-war world order were held by the U.S. secretary of state and by the foreign secretaries of all the Latin American countries except El Salvador and Argentina, resulting in the Act of Chapultepec of 6 March 1945. The Act included a framework for the negotiation of a regional security treaty. It also shaped Latin American pressure during the United Nations conference in San Francisco for clauses in the UN Charter to facilitate regional collective defense, under Article 51.

Initially, the security conference was planned to be held in Rio de Janeiro in October 1945 but it was postponed to March 1946. The March 1946 date was also postponed indefinitely. Disputes between the United States and Argentina's Juan Perón (President from 4 June 1946) led to the delays. The American concern, alongside that of some countries in South America regarding Peronism raised the possibility of including collective intervention to preserve democracy in the security conference. During the delay, global tensions between the United States and Soviet Union grew. In light of the developing Cold War and following the statement of the Truman Doctrine on 12 March 1947, the United States wished to make those^[which?] new anti-communist commitments permanent, as did many anti-communist leaders in Latin America.^{[citation needed]}

History

Signing

The Inter-American Treaty of Reciprocal Assistance was the first of many so-called "mutual security agreements", and the formalization of the Act of Chapultepec. The treaty was adopted by the original signatories on 2 September 1947 in Rio de Janeiro (hence the colloquial name "Rio Treaty"). It came into force on 3 December 1948 and was registered with the United Nations on 20 December 1948. With the exceptions of Trinidad and Tobago (1967) and the Bahamas (1982), no countries that became independent after 1947 have joined the treaty; Canada is yet to become a member, though it already has separate defense commitments with the United States.

Cold War

As revolutionary and nationalist governments spread through Latin America through the 1950s and 1960s, the fear of a shared enemy that was experienced during WWII dissipated and the idea of defensive cooperation became strained. According to Slater, many Latin American governments participating in the Treaty sought "to insulate the hemisphere from rather than involve it in world conflict", though the United States pushed the smaller countries towards confrontation with its ideological adversaries. Latin American governments then began to view inter-American collaboration as bending to the will of the United States, forfeiting their sovereignty.

Though the Cold War overtones of the Rio Treaty became increasingly evident, during the immediate post-war years, Long argues that it was more closely tied to pre-WWII regional antecedents and, even, Latin American diplomatic pressure. Long states, "Despite many Latin American concerns about the United States’ ultimately interventionist nature, Latin American diplomats cited the Monroe Doctrine and United States-led Pan-Americanism in support of a grand bargain that would extend and institutionalize U.S. engagement while restricting unilateralism." However, the United States' often considered adherence to the Treaty's principles of nonintervention as secondary to its Cold War concerns.

Though the action of the United States during the 1954 Guatemalan coup d'état and the 1961 Bay of Pigs Invasion raised questions among Latin American governments, the unilateral approach of the United States invading the Dominican Republic in 1965 during the Dominican Civil War, before the OAS's Inter-American Peace Force was organized, caused many members to believe that the United States did not respect the ideals of multilateralism. Conversely during the Falklands War in 1982, the United States favored the United Kingdom arguing that Argentina had been the aggressor and because Argentina had not been attacked, as did Chile and Colombia. This was seen by most Latin American countries as the final failure of the treaty.

21st century

In September 2002, citing the Falklands example and anticipating the invasion of Iraq, Mexico formally withdrew from the treaty; after the requisite two years, in September 2004, Mexico ceased to be a signatory. In 2008, the Union of South American Nations (UNASUR) created a new regional security council to manage their own defensive objectives. On 5 June 2012, Bolivarian Alliance for the Americas (ALBA) countries Bolivia, Ecuador, Nicaragua, and Venezuela, under the leadership of leftist governments, initiated the retirement from the TIAR, a decision which the Obama administration described as "unfortunate" but respected. The treaty was officially denounced by Nicaragua on 20 September 2012, Bolivia on 17 October 2012, Venezuela on 14 May 2013, and Ecuador on 19 February 2014.

Invocations and considerations

The treaty was invoked numerous times during the 1950s and 1960s, in particular the unanimous support of the United States' naval blockade during the Cuban Missile Crisis. In 2001, the United States invoked the Rio Treaty after the September 11 attacks.

In 2019 during a presidential crisis in Venezuela between incumbent President Nicolás Maduro and president of the opposition-led National Assembly of Venezuela Juan Guaidó, the latter opened talks on rejoining TIAR. On 11 May, Guaidó sent a letter to Organization of American States (OAS) secretary Luis Almagro requesting that Venezuela be reinstated. On 29 May 2019, the National Assembly approved its return to the Treaty in a preliminary discussion. The National Assembly reiterated its approval to return to the treaty in July 2019.
