We are not privy to the parts of government that control international relations, maybe our security services , our diplomatic services, our ministry of defence , our treasury department, or suchlike provide something to France that they would not want to lose.
We are not a rogue state nobody is applying sanctions on us.
If the EU are purposefully vindictive to the UK it will have severe consequences for them and it would show them up to be what they are, a dictatorial bloc.
I can't get my head around the Scotland thing. If they have a referendum and the message is to leave England so we can be independent and not controlled by Westminster and it would allow us to join the EU and be controlled by Brussels. Can you see the adult intelligent population of Scotland buying that one.
