The alliance was closely tied with the Franco-Czechoslovakian Alliance. France's alliances with Poland and Czechoslovakia were aimed at deterring Germany from the use of force to achieve a revision of the postwar settlement and ensuring that German forces would be confronted with significant combined strength of its neighbours. Although Czechoslovakia had a significant economy and industry and Poland had a strong army, the French-Polish-Czechoslovakian triangle never reached its full potential. Czechoslovakian foreign policy, under Edvard Beneš, avoided signing a formal alliance with Poland, which would force Czechoslovakia to take sides in Polish-German territorial disputes. Czechoslovakia's influence was weakened by the doubts of its allies as to the trustworthiness of its army, and Poland's influence was undermined by fighting between supporters and opponents of Józef Piłsudski. France's reluctance to invest in its allies' industry (especially Poland's), improve trade relations by buying their agricultural products and share military expertise further weakened the alliance.
