It is y understanding he promised two thngs: no more territorial ambitions in europe, and he would leave the czecks alone afterwards. He quickly ignored both, setting up protectorate in bohemia and puppet ally in slovakia, then wanted danzig (also memel, but no one cares about memel). If he didn't completely dismember czeckslovakia, do you think he would have been able to negotiate the danzig corridor?
Second question since don't want to spam discussions: if hitler took moscow in 1941, what are the chances of negotiated settlement? at this time hitler and stalin were negotiating peace in stockholm, stalin demanding white peace and hitler demand sattelite ukraine. Do you think stalin would say yes to satellite ukraine if moscow is taken? Do you think hitler would demand more land and turn stalin off (even if stalin would say yes to ukraine)? what if because moscow is taken northern and southern fronts collapse?
