How did expansionism pave the way for World War 2?

Expansionism played a crucial role in paving the way for World War II by creating aggressive nationalist sentiments and territorial ambitions among nations. Countries like Germany, Italy, and Japan pursued expansionist policies, seeking to acquire more land and resources, often at the expense of neighboring nations. This aggressive posture led to conflicts and tensions, particularly in Europe and Asia, undermining diplomatic relations and contributing to the outbreak of war. The failure of appeasement strategies further emboldened expansionist regimes, ultimately setting the stage for global conflict.
