Keith,

The problem is not with Paisley, Adams etc.
Paisley is 81 years old and wants to go down in history as a peacemaker ?. Adams and McGuinness want a unified country (all 32 counties) and will do nothing to destroy the reaching of that goal.
The real problem won't raise it's head until the day Nationalist do become the majority in the north. That day will not be too long in coming especially when Sinn Fein also make gains in the elections in the 26 counties. When hard line loyalists are faced with the real prospect of a United Ireland, then the riots will start and bombs and guns will come out again, believe me.
As a nationalist I hope and pray that I am wrong but I doubt it.

Only time will tell.

In the meantime let us enjoy the dream of a lasting peace.
