importantly implemented a labor agreement with Mexico, known as the Bracero Program. Mexican agricultural workers were brought under contract to the U.S. to do mainly agricultural labor as well as harvesting timber in the northwest. The program continued in effect until 1964 when organized labor in the U.S. pushed for ending it. In 1940 Roosevelt appointed Nelson Rockefeller to head the new, well-funded Office of the Coordinator of Inter-American Affairs. Anti-fascist propaganda was a major project across Latin America, and was run by Rockefeller's office. It spent millions on radio broadcasts and motion pictures, hoping to reach a large audience. In addition to propaganda, large sums were allocated for economic support and development. Madison Avenue techniques generated a push back in Mexico, especially where well-informed locals resisted heavy-handed American influence. Mexico was a valuable ally in the war; many of the long-standing disputes about oil were resolved and relations were the warmest in history. The usually strident anti-American voices on the far Left were quiet because the U.S. and USSR were allies. After years of debate, Mexico sent a small air unit into the war in the Pacific. An arrangement was made whereby 250,000 Mexican citizens living in the United States served in the American forces; over 1000 were killed in combat.

During Avila Camacho's visit with Truman near the centenary of the Mexican–American War, Truman returned some of the Mexican banners captured by the United States in the conflict and praised the military cadets who died defending Mexico City during the invasion. For bilateral relations between the U.S. and Mexico, the end of World War II meant decreased U.S. demand for Mexican labor via the guest-worker Bracero Program and for Mexican raw materials to fuel a major war. For Mexican laborers and Mexican exporters, there were fewer economic opportunities. However, while at the same time the government's coffers were full and aided post-war industrialization. In 1946, the dominant
