How is World War 2 an ideological war?

World War II is often considered an ideological war because it pitted opposing belief systems against each other, primarily fascism and totalitarianism versus democracy and liberalism. The Axis powers, led by Nazi Germany and Imperial Japan, sought to expand their empires and impose authoritarian regimes, while the Allied powers aimed to preserve democratic governance and human rights. This clash of ideologies fueled the conflict, as Propaganda on both sides portrayed the war as a struggle between good and evil, shaping national identities and justifying military actions. Ultimately, the war's outcome significantly influenced global political structures and ideologies in the post-war era.
