No Deal- Hard Brexit-Hard Border is inevitable and it's not a matter of choice.
There are 3 parties to this game: the UK , the EU and the Irish (all of them, North+South).
A compromise is achievable at the last minute about free trade, free movement and the so called rebate.
But in order to avoid a hard border between NI and Eire, NI needs to be part of the common market. It is a sensible solution, if it wasn't that the British government cannot accept for fear of losing face. Not that they have any face left, but they are good at pretending because the media is still pretty much Tory friendly.
No custom union, no soft border.
Hard border means repudiation of the GFA. In other words, prepare for NI to be annexed to Eire any time soon. Scotland will follow.
Bring it on!
