At the time of the end of the war in Europe, Juin was in the United States, where he represented France at the San Francisco Conference. In the immediate post-war period he continued with his task of rebuilding France's armed forces. This was made difficult by the ending of American Lend-Lease aid, and the military commitments to the Allied occupation of Germany, and in North Africa, Syria and Italy, where the 1947 Paris Peace Treaties made some adjustments to the border. The major looming crisis, though, was the Indochina War. Juin lost his direct access to the President when de Gaulle left office in 1946, and his plans for an Army large enough to handle France's commitments had to be scaled back.
