Or we can completely pull up the drawbridge and go it alone - but only the hardcore Brexit headbangers seriously want that!
I've just stumbled across an example of just such a headbanger.
http://www.theweek.co.uk/71732/vladimir-putin-should-be-running-europe-says-bernie-ecclestoneThat's the sort of company Brexit campaigners are keeping.........
Now we know that guy's a joke, but actually it's not funny. In fact, nothing about this referendum is funny - I honestly believe it's potentially the most serious decision we will have to take in most of our lifetimes, and the consequences of getting it wrong are unknown, and could be catastrophic. What is known is that Putin would be delighted to see the UK leave the EU, because it could very well be the start of a partial or even complete break up. And of course, ISIS would be delighted as well. You know what the Romans used to say, 2,000 years ago: Divide and Conquer.
And then there's the Scots, who are expected to vote 'remain' by a sizeable majority. That would probably lead to another independence referendum, and the result could very well be different this time. That leaves England, Wales and Northern Ireland out in the cold - and how long would Northern Ireland stick with us, once it is policing a land border with the EU?
Scary times.
