But this isn’t about a fictionalised Account of WW2 as the real war is hardly mentioned or only in passing. No it’s about how fascism and right wing ideology can pollute a nation and how that seed can grow and how history can often be decided on the smallest of margins.
Btw the same was true here as large members of chamberlains war cabinet were in favour of sue ing for peace with hitler to broker some firm of A deal, a fact largely downplayed now or even forgotten all together in some cases. As don’t forget Hess Germany’s second in command flew all the way to the uk to meet with high ranking British officials ... why did he do this who was he due to meet and how far advanced were these plans.
Churchill was one of the few that was opposed to the idea of an form of appeasement or capitulation and could see how dangerous this regime truly was.
I'm not sure there were "large" numbers in Chamberlain's cabinet who wanted to sue for peace, but certainly some did. The majority - reflected in the country did not want to sue for peace, nor appease Hitler.
Hess' mission is generally regarded as something he did unilaterally. The only influential person he knew was the Duke of Hamilton who it is clear didn't know Hess was coming.
History is written by the victors. It's this alone that spawns so many conspiracy theories which are fuelled by so many documents still being kept secret.
