Reduced US intervention in Latin American internal affairs marked a significant shift in inter-American relations. For example, the United States abrogated the Platt Amendment, which had granted it the right to intervene in Cuban affairs, and withdrew its Marines from Nicaragua. This fostered a greater sense of autonomy and self-determination within the region.
This shift in policy, initiated in the 1930s, aimed to cultivate improved diplomatic relations and strengthen partnerships in the Western Hemisphere, particularly during the rise of fascism in Europe. Cultivating stronger ties with Latin American nations was deemed crucial for hemispheric security and defense. This period saw increased Pan-American cooperation on issues ranging from trade to cultural exchange.
