The United States’ steadfast refusal to recognize the Soviet annexation of Estonia, Latvia, and Lithuania played a crucial role in maintaining hope for their eventual independence for five decades. This policy acted as an international cornerstone, influencing the actions of other Western nations. Specifically, the 1940 Welles Declaration, issued by acting Secretary of State Sumner Welles, is highlighted as a pivotal moment. The declaration significantly aided Estonia and the other Baltic states in establishing their legal and moral standing against the Soviet occupation. The US is credited with providing the most substantial support to the Baltic states in challenging the legitimacy of the 1940 annexation. This consistent stance ultimately contributed to the restoration of Estonia’s independence, offering a legal and moral framework for its claim. The Welles Declaration remains a celebrated event in Estonian history.
