What if Nazi Germany did not invade Poland?

[Domen]

The best thing may have been their invasion of Poland which put an end to appeasement.

But at what cost for Poland. Apart from Germany Poland was the biggest loser of WW2. But (Western) Germany after WW2 received $$$ financial support for reconstruction. Poland - which found itself on the other side of the Iron Courtain - did not receive anything.

In 1945 Poland was "liberated" from the German occupation only to found itself under Soviet / Communist occupation one moment later.

And lost so many civilians and soldiers. For what? Polish soldiers who fought alongside the Western Allies could not return to their country after WW2 - those who returned were persecuted by Communists. Home Army members were also imprisoned, persecuted, some executed by Communists.

In exchange for Eastern territories - Poland received land in the West as a "gift" from Stalin. But that land was devastated. Cities like Wroclaw were completely demolished, because Waffen SS and Wehrmacht defended them to the last building destroyed by Soviet artillery.

Warsaw was also demolished - after the 1944 Uprising Hitler ordered to destroy what remained of Warsaw. Stalin did nothing to stop him.

Churchill and - especially - Roosevelt - sold Poland to Joseph Stalin's regime. Communism was not much better than Nazi occupation.

Today nobody in the West remembers the Polish contribution to Allied victory in WW2 anyway. Jewish organizations blame Poland for doing not enough to save Jews from the Holocaust. And - strangely - American Jews seem to forget that they observed sufferings of European Jews and did nothing for so long time. Even later (from December 1941 on) American Jews did almost nothing to save European Jews. When information about death camps - including that from Poles, like Jan Karski for example - reached Western Allies - they did nothing to stop the massacres.
