The British and French were already rearming as fast as they could and Danzig would have been an acceptable price to give them an additional 6-12 months to close the gap on Germany. This would be most noticeable in relation to airpower, since British aircraft production alone in 1940 would have seriously challenged the Luftwaffe. The Heer attempting the blitzkrieg without the OTL Luftwaffe dominance would have been interesting.Things hold off for a few more months and then Hitler being Hitler he either goes after Poland again or just goes West. It would buy a few more months for the Allies to work out the kinks in their plans, build a few more guns and have Poland prepare properly for exile when the axe finally falls but it probably wouldn't' change much from the OTL phony war. Any peace now is temporary and the Allies know it, all they can do now is but a little time to finish rearming.
