And the Germans joined to cleanse themselves of genocide and apply for readmission to the human race. While the French only joined because they wanted to protect their inefficient farmers from commercial competition.
The British joined to screw the French by splitting them off from the Germans that and of course their foreign policy objective for at least the last five hundred years which has being to create a disunited Europe.
I don't think everyone here is familiar with "Yes, Minister", so it would probably be best if you quote it.
For anyone else interested, the parent paraphrased a scene [0] from the legendary British sitcom "Yes, Minister" (~early 80s) where the civil servant Humphrey explains, in the most cynical manner possible, how the EU (at the time EEC) came to be.
You're most likely right, fortunately I don't possess quite the level of cynicism that my comment might have suggested. I do hope there was no one who believed my comment was made in anything but jest (at the expense of it's parent commenter), that would be disappointing.
I was present on a talk about the EU given by an UK official back in 2014. At that time the person didn't even knew how many members the EU had (Croatia was just admitted) and they were pretty open that they are not really interested to know. When I've been to the UK, two years earlier, a bus driver that I talked to was afraid that eastern europeans will come and take his job. I perfectly well know the UK relationship with the EU, but trust me when I tell you that giving some numbers does not reflect reality. Maybe because the UK considered itself a winner in WWII and wasn't ruined from it like France and Germany, or maybe because of Soros and black Wednesday, or for whatever reason,but Brittan was never a cornerstone of the EU the way France and Germany are, which is the thing the GP was trying to imply and I definitely disagree.
