The author likely views the Treaty of Versailles as a mixed result for democracy. On one hand, the treaty sought to promote democratic values by holding Germany accountable for its actions during World War I and promoting self-determination for various countries. However, the harsh terms imposed on Germany, which many argue were too punitive, ultimately contributed to economic instability and political unrest in the country, paving the way for the rise of authoritarian regimes such as the Nazi party. Overall, the author may see the Treaty of Versailles as a complicated and somewhat problematic outcome for democracy.
