A. J. P. Taylor made a curious argument that due to an accident of geography, as long as the Poles resisted incorporation of Danzig into the Reich, Hitler could not get Danzig without launching an all-out war with Poland--he couldn't just seize the city like Memel because the only adjoining German area (East Prussia) was cut off from Danzig by the unbridged Vistula! Leaving aside the fact that by the time the war broke out (indeed for some months before that) Hitler was no longer interested in Danzig but in the destruction of Poland, I am not convinced that Hitler could not have limited the fighting to Danzig and the Corridor if he had wanted to. If he had done that and emphasized the limited nature of his demands, it is likely that, had Hitler not seized Prague, Great Britain and France would have acquiesced.
Esp as it was only six months since Poland herself had seized Teschen from Czechoslovakia. Expect a shrug and an observation that "What goes around comes around".
