Answer:
There were several factors that contributed to the high death toll during World War II.
Step-by-step explanation:
One factor was the intensity of the fighting, particularly on the Eastern Front where the German and Soviet armies fought a brutal and costly war. The use of new technologies, such as tanks and aircraft, also increased the number of military casualties.
Another factor was the intentional targeting of civilians by both sides. The bombing of cities, such as the Allied bombing of Dresden and the German bombing of London, caused significant civilian deaths. The Holocaust, in which six million Jews and other minority groups were systematically murdered by the Nazi regime, also contributed to the high civilian death toll.
The use of forced labor and the relocation of civilians to areas of military operations also led to civilian deaths. For example, the Japanese forced thousands of Chinese and Korean civilians to work on military projects, and many of them died due to harsh conditions and abuse. The Soviet Union also relocated many civilians from the Western regions of the country to the East in order to evacuate them from the advancing German army, and many of these civilians died due to the harsh conditions of the evacuation.
