You are assuming in the absence of the royals none of that would have happened. How can it not be an assumption. It’s like proving a negative.
I’m saying that in the absence of CULTURAL LEADERSHIP, Europe would have collapsed. The Royal Family’s sole responsibility in their Constitutional Monarchy is just this.
Churchill was one of the ONLY people in Parliament that understood WWII to be a CULTURAL battle, and that France had surrendered PRIOR to Germany invading it.
Again, without the Royal Family - no Churchill. He was not a popular politician - at all - until Germany invaded Norway. Why do you think Chamberlain even had a chance to negotiate with Hitler in the first place?
AGAINST the advice of the Royal Family, Chamberlain was sent to try to make a deal. “Peace in our day.”
It’s not like the Brits came out of WWI psychically unscathed. When they started talking about ‘The War to End All Wars’, they meant it, given that in the history of European war, WWI was, well, shattering to all involved.
