The Taoiseach says the hard-line Democratic Unionist Party is keen to see the new Northern Ireland institutions succeed.
Bertie Ahern believes the DUP's re-nomination of its two members of the Belfast-based executive after the IRA move on arms decommissioning, is a clear signal.
The Taoiseach says the political representatives of the loyalist paramilitaries in Northern Ireland have to help maintain the peace process moves.
He added: "I have long felt that the DUP very much like the assembly - they also like the executive, but from a slight distance.
"Maybe they don't like some of the other parts of the agreement and really I think they feel they must oppose these things.
"But in their hearts, I think they are probably glad, as I am that we are moving on this week."
