Think carefully, junior. He is predisposed to not giving an f about your economy and he just might pull the trigger to escalate things to a degree the EU cannot stand given its internal weakness. Better to play nice, actually act like a friend and ally, and avoid the worst possibilities. The EU could choose to do that but if they choose a show down I assure you they will take the worst of it.
They have more skin in the game and thus more to lose. Why pick a right when a fight can be easily avoided? Especially since the terms offered are extremely reasonable and amount to the status quo?
Yes, well, that's the thing. Its not about punishing the UK. It's about not rewarding behavior that proceeds from the assumption that the EU is there for the UK to avail itself of, without having to put anything back in — unlike what actual membership entails (a lot of which the UK INSIDE EU had managed to negotiate away anyway). Now, it's STILL funny how you seem to think that this was all built and maintained so that the UK should get all the benefits of the little EU serfs, and if they make a peep about it The Mighty US will punish this uppity behavior.
Sure, you can try. Frankly, with Trump I think you will, regardless of how the divorce between the UK and the EU plays out. Trump has as good as promised a couple of trade wars. Even funnier, the whole POINT is that the EU is looking out for itself. And equally funny, for all your scorn directed against the EU and Europeans, CLEARLY they have somehow managed to build something of actual and considerable value. Otherwise you would never be this hot under the collar. And final irony, considering how that works, the EU CANNOT give the UK what it ostensibly wants here (judging from May's speech) without triggering precisely the kind of centrifugal processes that could become a threat to it — which would potentially scupper the common market, leaving the UK just as wrong-footed.
So I suppose you will just HAVE to unleash the Mother of All Trade Wars against the EU, because that's how reality works. (There's no actual protection form threats and bullies you know — except giving in to them tends to be a bad idea — even when it's funny how you're gagging for the US to play that role.) The EU's first order of business it to protect itself, and that rules out just allowing the UK all the benefits and none of the chores of upkeep.
What you're suggesting is fundamentally anti-EU anyway, which kind of rules out any of it having any attraction for the EU. And the antithesis of free trade. But then, so is Trump. And likely so will America be on his watch. I suggest the UK sign a deal with his US, and find out how THAT works.
The way the US is set up, Trump CAN all by himself start half a dozen trade wars without consulting anyone. Now, no one wins a trade war. But surrender to threats has never been a defensive strategy. No one can stop Trump from doing this, if he so choses, but there's also no way of heading it off by giving up defense of the EU common market either. Either way Trump will wreck something. The only choice is what to defend. And a UK dead set of leaving the EU, while demanding all benefits, is not it.
