I'm British but managed to hop a border years ago so I don't really have a dog in this fight and people sometimes tell me to shut up. I never do. People also tell me that I jumped out of a frying pan and into a bonfire since I now live in Trump-World...but that's another story.
What I see over there is you are all at the mercy of a Prime Minister who, while often being claimed to be vulnerable and weak, is actually impregnable. She can do whatever she wants, and if what she wants is to screw over all those ungrateful cretins who criticise her then so be it.
Why is she impregnable? She is impregnable because no one else wants her job At This Time! Mogg and Gove and Boris all understand that Brexit is a poisoned chalice and though they might have designs on leadership, they do not want leadership under these circumstances. Who in their right mind would? Brexit is going to hurt the UK and it's people no matter which way it goes, certainly in the short term, so none of the Three Brexiteers want to be tarnished with that taint and will thus stay outside of it. Far better to stay outside the tent pissing in and say later that if they had been leader things would have been much better for the country, than have their words put to the test.
So, if I was Theresa May, I would be tempted to hit back at the critics and give the bastards the very worst deal I could out of pure petulance and malice. Hopefully May is a better person than I am. If she isn't then you are, indeed, all fucked.
