There is a lot of truth in that article, I think. I agree it is possible Brexit could make a united Ireland arrive earlier than it would otherwise. But the opposite is also true: the DUP's stance is driven as much by preventing reunification, in my opinion, than any of the proposed benefits of leaving the EU. And hence delaying reunification is a major factor in what sort of Brexit we end up with, albeit indirectly. The "border in the Irish sea" is arguably the biggest single factor whether unification is earlier or delayed.

But some people - McGrath was one I think - were saying much the same as that article even before the vote.
