What European problems did president Woodrow face when working to help rebuild Europe after the war?

President Woodrow Wilson faced several challenges when aiding European reconstruction after World War I, primarily stemming from deep political and economic instability. The Treaty of Versailles, which he championed, was contentious and faced opposition both in Europe and the U.S., complicating its implementation. Additionally, the rise of nationalist movements and the spread of communism created further tensions, making it difficult to establish a cohesive and stable post-war order. These issues were exacerbated by economic hardship in Europe, leading to social unrest and a lack of cooperation among the nations involved.
