Motherland. Erudite.
I don't know how to approach the answer to your initial question. I don't have a clue what would have happened if Chamberlain declared war over the Sudetenland. I do know that between the wars certain politicians seemed to forget that the Ardennes was like a martial superhighway through Belgium (Franco Prussian War and WWI). Also forgotten TWICE during WWII. And that Poland, as James A. Michener reminds us, was historically conquered uncountable times throughout history because of it's lack of natural borders, mountains, rivers et. al.
The initial disasters of WWII would not have been averted. Only the time line, perhaps. In this vein, WWII becomes a question of 'when' not 'if'. I don't think history should lay it all on Chamberlain.
Some historians and some poets agree that a prudent man prepares for war during times of peace. I don't have to get cerebral with that since I grew up on Strategic Air Command bases and once, in October 1962, watched a wing of B-47's deploy for war from Lincoln AFB. We were prepared to slug it out with the Russians (and destroy the world) if we had to. I know it's insane, but you should see my 'crazy face'. In that light, I would say that Chamberlain (and every other world leader) was imprudent beginning in 1919.
A supporting thought - the terms of war are harsh but the terms of the peace must be peaceful. I give you the Treaty of Versailles and its never-ending punishment of the German people. It was a mindset that was supposed to be a foundation for peace in Europe. How could it be?
Another thought, since none of us can stop ourselves looking for parallels in the past to apply to current events - global unrest was perhaps as chronic a condition in Chamberlain's time as it is in ours. The decline and fall of the Spanish empire, Italians in Ethiopia, early pressures to transform the British Empire into a commonwealth of states, and the Japanese invasion of China all occurred in Neville Chamberlain's life time. These events seemed to gain velocity and frequency in the 30's. How are similar events (change the word to pressures) shaping today's world view? I don't know the answer to that and neither do the millions of people that are much smarter than I am. I do know that's it easy to vilify Chamberlain when one doesn't completely understand his world. Clearly he was not a fool but he was intransigent in the face of what contemporary diarists agree were the real threats.
In my youth and in my own time in the military I never met a person who thought that their primary job was to fight a war. Not one. The primary job was to preserve the peace by simply being ready to re-fight WWII if necessary. That is deterrence which is NOT an antonym for appeasement. Our other Roosevelt understood that quite well..."speak softly, and carry a big stick." Roosevelt described his style of foreign policy as "the exercise of intelligent forethought and of decisive action sufficiently far in advance of any likely crisis"[Wiki].
Here, another coin for Dowding who was way ahead of British foreign policy by preparing for an 'inconceivable' air war - the Battle of Britain. Dowding was vilified as a petty tyrant at the time and through his own intransigence was brought down by lesser men. My opinion. Modern American corollaries would be Schwartzkopf and Powell who had to face their own 'parting shots' from lesser men.
Summing up: Chamberlain does not get a pass but he must not shoulder all the blame. Guys who will do everything possible to prepare for war during times of peace are realists. In a leader, I prefer realism to 'fidgeting and dithering' which is often used to describe the Texas Republic's (in)actions after the Alamo and during the 'Runaway Scrape'.
Last, I know I am conditioned from birth to distrust Russians, but I disagree, with equanimity, that Putin is okay just because he's the least of the evils. That is crazier than anything I might have written here. :::Makes Crazy Face:::
Again, thanks for posting this thought-provoking debate, SysError.
