Why is WW2 remembered as total war?

World War II is remembered as a total war because it involved the complete mobilization of nations' resources and populations, blurring the lines between civilian and military efforts. Governments directed economies toward war production, and civilians were targeted through strategic bombing and other means, making them integral to the war effort. The conflict also saw the widespread use of Propaganda and the involvement of multiple theaters of battle, emphasizing the total commitment of societies to achieve victory. This holistic approach marked a significant shift in how wars were fought and their impact on both combatants and non-combatants.
