to intervene in the war. Diplomatic alternatives Though some politicians, such as Poland's Józef Piłsudski, who had proposed the Międzymorze federation at the end of World War I had attempted to forge a grand coalition of Central, Eastern and Balkan European states, a series of conflicts there had prevented the establishment of anything but a series of smaller, mostly bilateral, treaties. Poland, for example, had good relations with Latvia, Romania, Hungary and France (with the Franco-Polish Military Alliance) but poor relations with Czechoslovakia and Lithuania (after the Polish-Lithuanian War). Hungary had similar tensions with both Romania and Czechoslovakia. Such conflicts had prevented Poland from joining the Little Entente. Over the next two decades, the region's political arena had been largely dominated by treaties and alliances similar to the Polish–Romanian alliance.
