Oh really? Say, I'd hate to give away too much of the story before we even get there, but perhaps you can explain this map to us?
No, even after the crushing defeat of France, Hitler never sought the return of the European German territories given to France after the first World War.
Hitler did seek the return of the German colonies split up among the winners.
Much of the carnage of World War II in Western (and even Central) Europe could have been avoided if the west had done two things - forced the Poles into accommodating the demands of Germany for free access to Danzig and a common front against the true enemy, and more importantly, put aside (with the American elite) the antisemitism that prevented giving refuge to the Jews.
On Poland -- Hitler was never going to find a better negotiating friend than Neville Chamberlain.
Chamberlain was fully prepared to appease any reasonable demands Hitler made.
But when Hitler scr*wed Chamberlain over, big time, in Czechoslovakia, Chamberlain said, in effect: "never again."
The problem, of course, is that Hitler was not a dependable negotiating partner.
Indeed, what Hitler wanted was war, and is reported as disappointed that he didn't get war with Chamberlain at Munich in 1938.
So the issue was never: "could war be avoided?" but rather, "how much do the allies have to give in before finally drawing a line that will lead to war?" In 1939 Chamberlain thought he had given up enough already, and would soon be ready to confront Hitler.
As for refuge for Jews: most of the refugees who arrived in the US during that period -- late 30s to early 40s -- were Jews.
President Roosevelt did everything he could to both increase the number of Jews arriving here and to encourage other countries to accept Jewish refugees.
And his program was successful, in that nearly all German Jews and most Austrian Jews did escape before the war.
But the problem was that most went to countries like Holland (i.e., Anne Frank), and once overrun by German armies had no further chances to escape Hitler's clutches.
About those millions of Polish and other Eastern European Jews who died in the Holocaust -- there was never a suggestion or plan for them to immigrate here before the war. And once war began, Hitler closed the door on them.
