Dy, Didn't Hitler retake the Rhineland (which was a DMZ) and unite with Austria before he began the brunt of his genocide? And maybe he even waited until he took the Sudentenland. I can't remember for certain, but that seems like how it went. I did a 15-page paper on how WW2 was the Allies fault for school last year...but I didn't get as much into the genocidal aspect of it.
