It's a good that people in 1940 seemed to have a bit more backbone than some Remainers today.
Perhaps it would help them too? Seems like they are being a bit petty about things, like the kid having a hissy fit so he takes his ball away. We co operated with europe well before the eu existed, we still can, but on equal terms.
In your idea, you need to understand those that are taking the ball away in a hissy fit is.... Us, the UK.
You have to remember, we have not been kicked out of anything. We are picking the ball up and taking it home. Why do you think the others are not too worried about what we think ?
Co operating is 1 thing. It is totally different to the best deal !
