A thought occurred to me earlier today - why was Danzig given to Poland after WWI, and not Koenigsberg? Both of them are major Baltic Sea ports, so either of them could have been made the Polish Corridor. Why was Germany partitioned in such a way that made its 'lost' territories more obvious, and basically invited Germans to desire the land back to have an overland route to their East Prussian exclave? From my point of view, it would've made far more sense to give OTL East Prussia - or at least part of it - to Poland. I'm aware that there's the issue of West Prussia having a greater number of ethnic Poles, but surely the populations could've been shuffled around appropriately?
And, of course, what if this had been the case, with a Polish East Prussia and no German exclave?
