Yalta and Potsdam

De Gaulle was never invited to the summit conferences of Allied leaders such as Yalta and Potsdam. He never forgave the Big Three leaders (Churchill, Roosevelt and Stalin) for their neglect and continued to rage against it as having been a negative factor in European politics for the rest of his life.

After the Rhine crossings, the French First Army captured a large section of territory in southern Germany, but although this later allowed France to play a part in the signing of the German surrender, Roosevelt in particular refused to allow any discussion about de Gaulle participating in the Big Three conferences that would shape Europe in the post-war world. Churchill pressed hard for France to be included 'at the inter-allied table', but on 6 December 1944 the American president wired both Stalin and Churchill to say that de Gaulle's presence would "merely introduce a complicating and undesirable factor".

At the Yalta Conference in February 1945, despite Stalin's opposition, Churchill and Roosevelt insisted that France be allowed a post-war occupation zone in Germany, and also made sure that it was included among the five nations that invited others to the conference to establish the United Nations. This guaranteed France a permanent seat on the UN Security Council.
