If they had not agreed to that "truce," there would have been war between the Nazis and Soviets in the event that the Nazis were crazy enough to invade Poland. The reason why they did it, imo, is because they had the guarantee that the Soviets would not intervene.

And, in a fight between the two then? Considering that if the French and Brits had bothered to attack while Nazis were in Poland, they would have rolled them up, I'll give you three guess as to what a Soviet attack would have done to them.
