ChatGPT does not agree: During World War II, the Allies suffered significantly more casualties than the Axis powers. The Axis (Germany, Japan, Italy, and others) lost about 8 to 10 million people, including both military and civilian deaths. Germany alone accounted for roughly 5 to 6 million of these. On the other hand, the Allies (including the Soviet Union, China, the United States, the United Kingdom, and others) saw around 50 to 55 million deaths. The Soviet Union had the highest number of casualties, with 24 to 27 million, mostly civilians. China also suffered heavily, with 15 to 20 million deaths. The higher Allied losses were largely due to massive civilian casualties and widespread destruction in the Soviet Union and China.
