When the governments of the Latin American states were taking part in the negotiations leading to the founding of the UN, they could hardly have done so with nostalgic memories of the League of Nations. The League had provided no protection to the Caribbean countries from interventions by the United States, and, largely because of United States protests, it did not consider the Tacna-Arica and Costa Rica-Panama disputes in the early 1920's. Furthermore, Mexico had not been invited to join; Brazil withdrew in 1926; and Argentina and Peru took little part in League affairs. The organization was regarded as being run mainly for the benefit of European states with the aid of what Latin Americans called an “international bureaucracy,” in which citizens from the southern hemisphere played minor roles. The United States was, of course, not a member, and both the reference to the Monroe Doctrine by name in Article 21 of the Covenant and the organization's practice of shunning any attempt to interfere in inter-American affairs against the wishes of the United States made the League in its first decade a remote and inefficacious institution to countries that were seriously concerned about domination by Washington.
