Why didn't the not provide a lasting peace?

The treaties often failed to provide lasting peace due to unresolved underlying issues, such as territorial disputes and ethnic tensions, which were not adequately addressed. Additionally, the imposition of harsh penalties on defeated nations led to resentment and the desire for revenge, fostering future conflicts. Economic instability and social unrest further complicated the peace process, making it difficult to establish a sustainable resolution. Ultimately, the lack of genuine reconciliation and cooperation among nations allowed historical grievances to resurface, undermining long-term peace efforts.
