There are many reasons and theories why people voted for Brexit.
One of my theories is that a significant contributor to the zeitgeist was the 2016 British war comedy film “Dad’s Army”. The film was based on the BBC television sitcom Dad’s Army. It was set in 1944.
The story sees Catherine Zeta-Jones play an elegant journalist, who is sent to Walmington-on-Sea to report on the British South Coast defences. All’s well that ends well with Catherine Zeta-Jones being unmasked as a spy and the Walmington-on-Sea Home Guard platoon being triumphant over the German might.
Unlike the sitcom the film opens with the German military high command looking at a map of Great Britain and asking themselves who these people think they are resisting the German invasion plans.
The film immediately reverts to the familiar animated sequence of swastika-headed arrows approaching Britain and then comes the show’s theme tune, “Who do you think you are kidding, Mr Hitler?”

“Who do you think you are kidding, Mr Hitler If you think we’re on the run?
We are the boys who will stop your little game!
We are the boys who will make you think again!
‘Cause, who do you think you are kidding Mr Hitler If you think old England’s done?”

Change the name in the first and penultimate lines to Jean-Claude Juncker and all becomes clear (or does it – only time will tell)
