How was the Versailles treaty unable to meet challenges of postwar problems?
It humiliated Germany. The treaty included a war- guilt clause that forced Germany fo admit sole responsibility for starting WWI. Also for three years the Russians had fougnt on the side of the Allies, suffering higher casualties that any other nation. However, because Russia was excleuded from the peace conference, it lost more territory than Germany did. This caused Russia(or Soviet Union) to be determined to gain its territory back.
