No, I conclude from Pat's language...
The cost of the war that came of a refusal to negotiate Danzig was millions of Polish dead, the Katyn massacre, Treblinka, Sobibor, Auschwitz, the annihilation of the Home Army in the Warsaw uprising of 1944, and 50 years of Nazi and Stalinist occupation, barbarism and terror.
...that Pat blames Poland for the war. If only they had negotiated, the tanks would never have rolled. That Pat thinks they deserved what happened.
Do you agree with Pat's "logic"?
Option 1: Stand intransigent and rely on Chamberlain's guarantees. Outcome 1: Chamberalain's word was worthless, Poland was devastated, its population decimated or worse, the country was divided, and suffered 50 years of communist oppression.
Option 2: Recognise we are in an untenable position and try to negotiate something. Outcome 2: Historically unknowable since we took option 1, which turned out to be the worst of all possible worlds.
None of that analysis is moral absolution or justification of Hitler.
Again Pat states these conclusions exactly where?
