Lots of if, ands, and buts here. Plus Hitler was a Sociopath, who relied on his instincts which made him a brilliant politician, but a horrible military commander.
P.S. Hitler hated the Jews, but he wasn't the only Euro who hated Jews. However, because he devoted so much money, personnel, materiel, and blood to destroying the Jewish race, he is the biggest promoter of Communism in the 20th Century. Why? Because he gave the Communists something they never had before nor after- the moral high ground.
Fact is, Hitler wanted Poland as an ally, he greatly admired Marshall Pilsudski, even attending a memorial service for him when he died.
But when Poland allied with England and France, Hitler decided that Poland must be eliminated.
There’s an interesting theory as to why Poles were subject to such harsh treatment compared with the other occupied countries.
The Nazis were convinced, despite Poles being considered Slavs, Poles and Germans mixed over the centuries, providing Poles with “good blood” that could be used against the Germans, if they weren’t eliminated as a race.
That explains why the Nazis never used Poles as guards at the Death Camps, the last thing they wanted to do was give a Pole a rifle.
