Think twice: If small coridors are indefensible against any determined attack, how do you explain the continued existence of Israel?
You must not loose strategic initiative, you must not trade land against peace until you know your opponent will deliver, but you must not think it's impossible either.
Well, Israel never fought a much more powerful enemy attacking from both sides of its corridor. Or did it? Also, continued existance does not preclude temporary loss of control over a corridor in all cases.
The war with France DID go away, and Britain alone would have been no hopeless venture, so I see no miscalculation before Germany started to divert their forces to Africa, the Balkans and last but not least the Sowjet Union.
It went away at a heavy cost, i.e. getting even deeper into the deadlock with Britain (with a pro-British USA farther complicating the matter). Conquering the USSR was always Hitler’s primary goal.
Since his plan to get at it resulted in the prolonged war with Britain, I stand by my assertion that it was a huge mistake.
Way back in September I wrote:
So, how do you prevent Germany going to war with Britain and France following their declarations of war? Hitler's ultimate objective was war with the USSR - but charging into it while at war with the Franco-British duo undefeated seems insane even by Hitler's standards. Or, by summer 1939, was there a chance that they would simply let Germany get away with invading another country after having guaranteed it?
You replied:
I don't know wether Hitler really thought that Britain and France wouldn't intervene at all, but he was certainly right in relying on Franco-British passiveness in the time frame when Franco-British passiveness was crucial, so I see no strategic miscalculation there.
Germany was doomed as soon as they DID attack the USSR with the Franco-British duo (or at least half of it) undefeated, but that is another story
I answered:
As of October 1939 managed to achieve his short-term goal (defeating Poland), but the war with France and Britain was not going to go away. As I understand it, the strategic miscalculation was tremendous. Surely it would not have been safe to charge into the USSR with two untouched, very hostile powers right on the western border?
I assumed that we were discussing what options Germany had after blundering into the war with Britain and France (and if they reached the point of declaring war, they certainly were hostile). Your response was:
France and Britain weren't hostile. They tried everything to appease Germany, and I don't think they'd be anti-German when the enemy is Communism alone.
When did we go back to discussing the appeasement era? Because Summer 1939 was already way past it (Britain and France would not have even tried for an alliance with the communists against Germany if the reds were considered the greatest threat).
No, the question is: Can Poland be such a fool to support Germany up to the point when it can freely reconsider?
Hmm. If Hitler started forcing himself on Poland, and the Poles decide that West won't offer any help, such support is possible. It may be worth remembering that, as of 1939, Hitler hadn’t started with his genocides yet.
Another question might be wether, in hindsight, it would actually have been foolish. Its answer would depend on wether Germany could:
-win a war with the USSR
-fight the West off/keep it out of the war altogether
-resist the urge to destroy ‘well-established’ clients as soon as physically possible, thus sending the message that nobody is safe with the damage to the Axis which this may imply
or not, questions I cannot well answer.
Poland’s OTL choices resulted in the unforgettable experience of complete loss of soverignity and years of occupation by hostile Nazis and the murder of a sizable part of the population (not only the Jews, but also a disturbingly high percentage of ethnic Poles) in which the intelligentsia were specifically targetted. And all this happened before the Soviets came for good. Even a direct transition to Soviet rule would have been preferable to OTL.
At the very least, Poland would be pissed of if they actually lost territory to the USSR.
Since the borders of Poland and the USSR were not defined before their war ended, technically it’s hard to speak of ‘losing’ territory. But the short answer is: Yes, if Poland fails to obtain certain areas it will most definitely be pissed. But how do annoyed Poles make the rise of Hitler more likely?
My guess is: No Non-Nazi Government, not even a right wing dictatorship, will go for "Lebensraum". Any German Government will demand all territories lost in WWI and see what they can get. Danzig is unlikely to ever be given up by Germany, so is West Prussia for Poland - which pretty much settles the agreement that Germany and Poland would have made sooner or later if Hitler hadn't come to Power.
