WARTIME DIPLOMACY

Franklin Roosevelt entered World War II with an eye toward a new postwar world, one where the United States would succeed Britain as the leader of Western capitalist democracies, replacing the old British imperial system with one based on free trade and decolonization. The goals of the Atlantic Charter had explicitly included self-determination, self-government, and free trade. In 1941, although Roosevelt had yet to meet Soviet premier Joseph Stalin, he had confidence that he could forge a positive relationship with him, a confidence that Churchill believed was born of naiveté. These allied leaders, known as the Big Three, thrown together by the necessity to defeat common enemies, took steps towards working in concert despite their differences.

Through a series of wartime conferences, Roosevelt and the other global leaders sought to come up with a strategy to both defeat the Germans and bolster relationships among allies. In January 1943, at Casablanca, Morocco, Churchill convinced Roosevelt to delay an invasion of France in favor of an invasion of Sicily (Figure). It was also at this conference that Roosevelt enunciated the doctrine of “unconditional surrender.” Roosevelt agreed to demand an unconditional surrender from Germany and Japan to assure the Soviet Union that the United States would not negotiate a separate peace and prepare the former belligerents for a thorough and permanent transformation after the war. Roosevelt thought that announcing this as a specific war aim would discourage any nation or leader from seeking any negotiated armistice that would hinder efforts to reform and transform the defeated nations. Stalin, who was not at the conference, affirmed the concept of unconditional surrender when asked to do so. However, he was dismayed over the delay in establishing a “second front” along which the Americans and British would directly engage German forces in western Europe. A western front, brought about through an invasion across the English Channel, which Stalin had been demanding since 1941, offered the best means of drawing Germany away from the east. At a meeting in Tehran, Iran, also in November 1943, Churchill, Roosevelt, and Stalin met to finalize plans for a cross-channel invasion.
