Resistance
Modern genocides have been stopped in various ways. The Nazi Holocaust during World War II ended only in the face of a massive external military onslaught mounted on two fronts, by both the Allies and the Soviet Union. Jewish and Soviet partisans, and resistance movements in Poland, Yugoslavia, Czechoslovakia, Norway, Italy, Greece, and France all inflicted significant casualties on Nazi forces, in some cases causing substantial losses, but such indigenous opposition played a secondary role in the defeat of the Hitler regime.
