You seem to think that the EU is made of sensible people. It's not. Indeed, Brussels is at the very root of the problem. The terms they'll offer will be humiliating.

I can assure you, that they'll be nothing that a UK gov can sign and we'll be displayed in a very, very public manner to make the Britons feel humiliated.
