The question of a united Ireland also won't have much to do with Irish nationalism either, IMO. It will, rather, have to do with assimilation into the EU, and with eliminating duplicate bureaucracies interfering with one another's work.

It will be practical matters, not nationalism, which will result in the reunification--just as it has been practical matters, not nationalism or unionism.

As to Paisley's and the DUP's influence, I stand by what I said. He and his party have influence in one tiny part of Europe, and they are irrelevant every place else. Totally irrelevant.

On the other hand, with Sinn Fein and progressives like the Greens, a handful of Labour party members, etc. forcing the political agenda more towards integration with Europe and the US, how relevant does British unionism remain? Answer: not very. Not in Ireland, not in Britain, and certainly not in Europe and the international community, where Paisley, the DUP and British unionism is seen as the dying dinosaur it is.
