The Soviet Union repeatedly declared intention to fulfill its obligations under the 1935 treaty with Czechoslovakia and defend Czechoslovakia militarily. A transfer of land and air forces through Poland and/or Romania was required and the Soviets approached about it the French, who also had a treaty with Czechoslovakia (and with Poland and with the Soviet Union). Edward Rydz-Śmigły rebuked the French suggestion on that matter in 1936, and in 1938 Józef Beck pressured Romania not to allow even Soviet warplanes to fly over its territory. Like Hungary, Poland was looking into using the German-Czechoslovak conflict to settle its own territorial grievances, namely disputes over parts of Zaolzie, Spiš and Orava.
