If Hitler did not make the pact with the SU then Britain and France would in that case, and Hitler would not be able to play any tricks after taking the rest of the Czechoslovakia early 1939.

Hitler already had problems making his generals believe in his ideas, he himself wanted to go to war for sure, but facing a definite two-front war by 1939 if attacking Poland, I am sure Hitler would have to think twice instead of going to war like that.
