While the European Allied countries did not have to pay reparations like Germany they did suffer economically because of the

economical crisis that hit the whole Europe after WW1.

Explanation:

Europe lost about 50 million people due to the war, the birth rate and the Spanish fever epidemic from 1914 to 1921. Roads and factories were destroyed and inflation raged in Germany, Austria, Hungary, Italy and Poland. The economic revival began only in 1939.
