The Brexiteers and Mrs May seem to be from the school that says you have to be willing to walk away from a negotiation to get the best deal. But surely Brexit is not a problem of this nature.
If there were a natural disaster the countries would get together and agree what to do about it. One would not say to the others, do it my way or we’ll do nothing. That’s insane.
It seems clear to me that a ‘no deal’ Brexit, maybe even the Brexit vote itself, is just such a disaster – when all sides would significantly suffer. To contemplate this, rather than negotiate a solution to the joint problem is , yes, insane.
Of course, some of the players in the Brexit game actually want this catastrophe to happen. The sane majority must not let this happen.
The comment applies to both sides, incidentally.
