Why was nationalism a cause of ww2?

Answer 1

Nationalism was a significant cause of World War II as it fueled aggressive expansionist policies among nations, particularly in Germany, Italy, and Japan. These countries sought to assert their dominance and pursue territorial ambitions, often at the expense of their neighbors. The Treaty of Versailles, which imposed heavy reparations and territorial losses on Germany after World War I, further exacerbated German nationalism, leading to the rise of Adolf Hitler and the Nazi regime. This extreme nationalism contributed to the breakdown of international relations and ultimately ignited the conflict.
