What were the consequences of the Treaty of Versailles for the concept of national self-interest?

The consequences of the Treaty of Versailles for the concept of national self-interest were mixed. On one hand, the treaty aimed to punish Germany for its role in World War I, imposing heavy reparations and territorial losses. This demonstrated that the self-interest of the victorious Allied powers took precedence over Germany's national self-interest. On the other hand, the treaty also led to the establishment of new nation-states and the principle of national self-determination, which allowed certain ethnic groups to pursue their own self-interest by forming independent nations. Overall, the Treaty of Versailles both challenged and supported the concept of national self-interest.
