Both countries pledged to resolve their problems by bilateral negotiations and to forgo armed conflict for a period of ten years . It effectively normalized relations between Poland and Germany, which were previously strained by border disputes arising from the territorial settlement in the Treaty of Versailles . Germany effectively recognized Poland's borders and moved to end an economically damaging customs war between the two countries that had taken place over the previous decade . Before 1933 Poland had worried that some sort of alliance would take place between Germany and the Soviet Union, to the detriment of Poland . Therefore, Poland had a military alliance with France . The Nazis and the Communists were bitter enemies of each other, so when Hitler came to power in 1933 the likelihood of hostile alliance seemed remote . </P> <P> One of the most noted of Józef Piłsudski's foreign policies was his rumored proposal to France to declare war on Germany after Adolf Hitler had come to power, in January 1933 . Some historians write that Piłsudski may have sounded out France regarding the possibility of joint military action against Germany, which had been openly rearming in violation of the Versailles Treaty . France's refusal might have been one of the reasons that Poland signed the German--Polish Non-Aggression Pact . </P>
