So before World War II, Poland collaborated with Hitler and although it did not yield to Hitler’s demands, it still participated in the partitioning of Czechoslovakia together with Hitler. As the Poles had not given the Danzig Corridor to Germany, and went too far, pushing Hitler to start World War II by attacking them. Why was it Poland against whom the war started on 1 September 1939? Poland turned out to be uncompromising, and Hitler had nothing to do but start implementing his plans with Poland.

Saying that Poland refusing to cede Danzig to Germany was the cause of WW2 is a bit iffy I think. Why is Danzig a legitimate target to cede while the Sudetenland was an outrage?

It would be nice if people were less easily impressed with blood and soil propaganda.
