"ODESSA (German Organisation der ehemaligen SS-Angehörigen; "The Organization of Former SS-Members") was an alleged Nazi-German fugitive network set up towards the end of World War II by a group of SS officers. With alleged ties to Argentina, Egypt, Germany, Italy, Switzerland, and the Vatican, ODESSA ostensibly operated out of Buenos Aires and helped Adolf Eichmann, Josef Mengele, Erich Priebke and many other war criminals find refuge in Latin America and the Middle East."
