Then there is the problem of those pesky migrants, who travel to RoI under FoM, then cross into NI through one of these unchecked borders.

Shove checkpoints in and the New IRA will target them.
There is no technology that can cope with remote checking of tanker full of milk from either side of the border, let alone simple checks on goods.
Move the border to the Irish Sea and the DUP will kick off.
NI farmers are particularly vulnerable to cheap beef imports.

Simplest solution is reunification. Would the DUP support the government if this was even whispered, let alone supported?
