Any soft border = customs moving to the mainland side. Inevitably the DUP will realise that they are on the other side of the UK border, and in effect part of a united ireland. The DUP can't let that stand,so you are both right - this could bring down the tories.

Also, no western nation has customs checks within its own borders, a soft irish border means that for the UK if we brexit.

This madness needs to stop.
