Spot on mate!
No one in the political elite, either in the UK or in the EU, ever envisage that anyone would ever want to leave the EU and just to be sure devised Art 50, (written by a Brit) this ensures the recalcitrant member either leaves on the EU's terms (i.e. sucks it up) or leaves without a deal (called crashing out).
We are now in a game of 'chicken' that May has to see it through, whatever the outcome, because she has nowhere else to go. The rest of the politicians at Westminster are wetting themselves about an 'accidental' no deal outcome and how they will explain this to their constituents. The EU is holding firm, behind Ireland (at least for the time being) but there are long glances across the table between those EU countries who will suffer very little by the UK departure and those that will get 'hammered' by a no deal.
No ones been here before, its Learning on the Job for all concerned. The experts and academics etc. will be writing books on this for the next quarter of a century, so at least someone will make some money!
Who will blink first?
