Actually Piłsduski's great dream had been to create a grand confederation encompassing Poland, Lithuania, Ukraine and Belarus approximating the Polish-Lithuanian Commonwealth (Rzplita Obojga Narodów). When he marched into Kyïv that had been his intention, but his ally Petlura was unable to stay in control, the Poles got pushed back to the gates of Warsaw and Ukraine ended up in Soviet hands.
Had Piłsudski's dream come true, the USSR probably would have never happened or at least it would have been far smaller. The expasnive and bellicose Japs would have probably attacked Russia from the east, re-Asianising the tsars' ethnically non-Russian acquisitions in much of Asia.
If we add Piłsduski's proposed (to France and England) pre-emptive strike against a still weak and underarmed Germany (early 1930s), the whole course of world history migth have been altered. Probably for the better, because WW2 might have never occurred.
