In a sense the situation here is not so straightforward. Of course we can accept that Irish nationalists who are conservative and not like the communist IRA are like minded and in a sense allies. However they do want Ireland to be a single nation as Ireland while we are generally in favour of the UK.
That having been said, it seems very clear that the GFA makes it only a question of time before Northern Ireland goes over to the Republic anyway.
An ideal situation would be if Ireland were also inclined to leave the EU and maintain the cordial links and freedoms with the UK that we had been building on and had in practice even prior to the idea of Schengen space, etc, in the EU.
