 Headquartered in Buenos Aires, ATLAS began an intense campaign across Latin America.Its propaganda emphasized that it wished to "humanize capitalism", and provide a "third way" in the Latin American labour movement (different from the pro-U.S. ORIT and the pro-communist CTAL), arguing that Latin American trade unions should build unity without 'external' interference.Vincente Lombardo Toledano, leader of CTAL, on the other hand sought unity in action between CTAL and ATLAS (which like CTAL took up anti-imperialist positions), a move which was rejected by ATLAS.
