Re: @anon: This is what it looks like outside the EU.
"The EU" is a group of member states, joined together by rules that they decide between them for the benefit of them all. The rules are everything.
Yes, the group of EU countries wants to stay a group, because of the many benefits the grouping brings. But that isn't the same as something called "The EU" that merely exists to have power.
Which is why Germany and France have not rushed to help the UK get a good deal at the expense of the EU: those countries think that remaining as EU member states is more important to their economies and citizens than supporting the UK in leaving the group.
