Germany might survive or take Britain down with her.

The reason for new documentaries recently(and books) is the release of more Secrecy Act Records including Churchill's and Eisenhower's own assessments, thoughts, expectations and contingency plans.

It seems these new records show that both Eisenhower and Churchill believed that had the Germans achieved their objectives and held Antwerp, that Hitler was more willing to gamble taking Britain down with him, than Churchill(even Eisenhower) were willing to sacrifice Britain and her Empire/Commonwealth to take down Hitler.

The both knew that if Churchill agreed to risk sacrificing the Royal Army to take Hitler down, it would also take down Britain and the Empire. No gov't would survie another hundred-fold Dieppe. Britain would probably pull out of the war as soon as Germany surrendered.

Losing that Army Group would lose Britain its remaining status at the Victory Table. Canada(Dieppe was bad enough) would probably pull out of the war even lose support for the Royal ties. The colonies would see Britain sapped of military strength and influence and pull out 5-30 years early.

It all came down to one crazy principle.

Hitler would be more willing to sacrifice his Western Army even the war to get revenge on Britain, taking her down with him,
than Churchill was willing to sacrifice Britain and her Commonwealth and Empire to see Hitler fall.

And don't tell me Hitler wasn't that crazy.

Everyone, including the Germans, thought that if Hitler had anything left, he'd have thrown it at the Russians, not the 'Anglo-Saxons'.
