I am all for revising understanding of history for the better as we learn more. But this film, like the novel it is based on, is not that at all, but rather an apologia and whitewash of Chamberlin's very real, naïve and ghastly mistake at Munich.
Robert's Harris' novel, Munich, on which this film is based isn't simply somewhat wrong, it is totally wrong. In fact Chamberlin was not thoughtful, and was NOT a skilled diplomat. He was a vain, pompous and petty dupe. The idea that he somehow outsmarted Hitler is ludicrous, Hitler got everything he wanted.
We even see in the crawl text at the of the film the claim that "The extra time bought by the Munich agreement enabled Great Britain and her allies to prepare for the war and ultimately led to Germany's defeat." Errr.. no. That is completely wrong. All the data on industrial capacity trends, submarine production, armored vehicle and aircraft production tends, as well as oil and other fuel reserves, shows that the UK and France were in a stronger position in 1938 than in 1939. The Munich agreement also had a massively deleterious effect on both strategic and popular views in the US and the USSR. It convinced Stalin to ally with Hitler. Which was the only way Hitler could invade Poland. The delay of the inevitable war resulted in the annihilation of Poland, the actualization of Japan's closer and more effective alliance with the Nazi's, and by all analysis made the holocaust 3x more effective by allowing the Germans to ally with the Soviets giving the Nazi more control of more of E. Europe where they mass murdered the Jewish populations. American isolationists got a massive boost from the blunder at Munich as well.
We know from Hitler's "second book" (go to youtube and search "Gerhard Weinberg Hitler's second book. For an excellent panel talk on it) we know that Hitler for considered the United States as the ultimate enemy of Nazis. He thought Great Britain would fold (and it initially did due to Chamberlin), that France would be easy to defeat if the war with them started in 1939 instead of 1938 (and it was), that he could fool the Soviets (and he he did for several key years). He thought the non-racial based nationalism of the US, which is to say the US's people's love of democracy, was the ultimate threat to the Nazis.
So in "Edge of War" we are left with a film that has some nice period elements, certainly fine acting, but is also severe disinformation on what went on at Munich. We know for a fact that Goering wrote the agreement, that no British changes were accepted, and that Chamberlin signed off without an argument which stunned even the Nazis.
