In the end I can see Eire becoming one nation again. I doubt this will be in my lifetime however.
The DUP (the Unionists) appear very much in the minority and this will go down further in the years ahead. No, Northern Ireland was a convenient political outcome in the last century and I can see a united Ireland this century. Clearly the DUP need appeasing, but this is the 21st century not a long time ago.
