Inter-American Conference on Problems of War and Peace was a 1945 multilateral meeting convened in Mexico City that brought Western Hemisphere foreign ministers and plenipotentiaries together to coordinate policy on collective security, peace treaties, and postwar order. Delegations from twenty-one American republics discussed relations with Allied Powers, approaches to the Axis Powers aftermath, and positions for participation in the United Nations. The conference produced resolutions influencing hemispheric cooperation, extradition, and regional diplomacy ahead of the San Francisco Conference.

Background and Origins

The conference emerged from wartime diplomacy rooted in earlier gatherings such as the Pan-American Conference (1933) and the Pan-American Union, which had institutionalized inter-American consultation alongside instruments like the Inter-American Treaty of Reciprocal Assistance. Pressure from the United States Department of State and representatives of Argentina and Brazil intersected with the strategic aims of Franklin D. Roosevelt and diplomats who had engaged at the Atlantic Charter and the Tehran Conference. The collapse of the Axis Powers and the approach of the United Nations Conference on International Organization created urgency for a unified hemispheric stance, drawing in foreign ministers who had participated in prior forums including the Buenos Aires Conference and the Montevideo Convention on Rights and Duties of States.

Proceedings and Agenda

Sessions opened under presidencies alternating among senior diplomats influenced by precedents from the Pan-American Union and organizational norms from the League of Nations experience. Agenda items reflected wartime transition themes: recognition of postwar governments such as the Provisional Government of Italy (1943) implications for Nuremberg Trials alignment, mechanisms for extradition and prosecution tied to instruments like the Hague Conventions, and principles for membership and voice at the United Nations. Debates mirrored diplomatic maneuvering seen at the Yalta Conference and the Potsdam Conference with national positions informed by legal doctrines from the Montevideo Convention and prior rulings of the Permanent Court of International Justice.

Participating Nations and Delegations

Delegations included foreign ministers and envoys from twenty-one republics of the Americas, many of whom had served in cabinets under heads of state such as Getúlio Vargas, Ángel Perón—via Argentine foreign policy apparatus—Manuel Ávila Camacho, and Ezequiel Padilla. Observers and advisers included representatives linked to delegations to the San Francisco Conference and legal experts with ties to the Hague Academy of International Law and universities such as Harvard University and Universidad Nacional Autónoma de México. Caribbean delegations from Cuba and Dominican Republic coordinated with Central American envoys from Guatemala and Costa Rica, and South American delegations from Chile, Peru, Colombia, and Venezuela presented positions shaped by regional treaties including the Treaty of Bogotá and precedents from the Organization of American States negotiation history.

Key Resolutions and Agreements

The conference adopted resolutions endorsing collective measures against aggression consistent with principles later reflected in the United Nations Charter, advocated for cooperative extradition arrangements informed by the Inter-American Convention on Extradition, and recommended mutual assistance in prosecuting war crimes referencing models from the Nuremberg Trials. It passed measures urging adherence to neutrality obligations similar to those debated at the Washington Naval Conference and encouraged hemispheric economic and diplomatic coordination that resonated with policies of the Marshall Plan architects. Texts forwarded to the San Francisco Conference sought to secure hemisphere representation and to articulate limits on intervention consistent with rulings from the Montevideo Convention and arguments advanced at the Havana Conference (1940).

Impact on Inter-American Relations and International Law

Resolutions influenced later practice within institutions such as the Organization of American States and provided legal and diplomatic groundwork for Latin American participation in the United Nations General Assembly. The conference contributed to doctrines addressing collective security in the Western Hemisphere that intersected with jurisprudence from the International Court of Justice and operational policies of the Pan American Health Organization and Inter-American Development Bank in the postwar period. Hemispheric alignment achieved at the meeting affected bilateral relations involving United States–Argentina relations, United States–Brazil relations, and multilateral bargaining at the UN Security Council.

Criticism and Controversies

Critics charged that major powers, notably United States Department of State actors and delegations sympathetic to United States foreign policy, exerted disproportionate influence, echoing controversies from the Good Neighbor Policy era and disputes linked to the Rio Pact negotiations. Dissenting delegations, including elements associated with Argentine policymakers and activists opposing Allied policies, accused the conference of marginalizing sovereign prerogatives and of preempting sovereign decisions later litigated before bodies such as the International Court of Justice. Additional controversies concerned the scope of extradition provisions and assertions that some texts replicated legal frameworks debated at the Nuremberg Trials without adequate safeguards for due process as articulated by jurists from the Hague Academy of International Law and scholars from Oxford University.
