Would the Pacific war delay the invasion of Poland?

How would the war against Japan affect a later German or Soviet attack on Poland?

It could delay the crisis until roughly 1942, giving Poland more time to modernize while Allied mobilization, American cooperation, and Soviet commitments in Asia make the European balance less favorable to aggression.

The war does not erase German or Soviet territorial ambitions. It can, however, postpone action while the great powers are mobilized together and while the Soviet Union is also engaged against Japan. Three additional years would give Poland time to improve tanks, aircraft, small arms, and defensive preparation. American participation in a successful coalition could also leave Washington tied more closely to Britain and France, making a later European war less isolated than the crisis of 1939.
