Sinn Féin and the IRA must overcome their innate "conservatism" and announce the permanent renunciation of violence, decommission their weapons, and sign up to the North's new policing arrangements, according to Minister for Foreign Affairs Dermot Ahern.
In a speech at UCD last night Mr Ahern laid out the steps he believed the Provisional movement had to take and the response required from unionism if stable political arrangements were to be put in place.
Referring throughout to Sinn Féin and the IRA as "the Provisional movement", he said they must resolve the issue of paramilitarism in a definitive way. He welcomed Gerry Adams's instigation of an internal discussion in that movement, but warned: "An ambiguous outcome offered as a take-it-or-leave-it will merely repeat the weary cycle of Sinn Féin salesmanship followed by unionist rejection and collapse."
He said the Provisional movement must first make a statement describing the outcome of their internal deliberations.
"The method by which that outcome is validated within the Provisional IRA will be critical, for in that method one will be able to assess its seriousness and completeness."
There will then be a verifiable record of what action is taken on foot of that. "Will all weapons and the capacity to use them in a campaign be fully decommissioned, and will this be duly verified by the Independent International Commission on Decommissioning?
"Will paramilitary activities as defined by paragraph 13 of the Joint Declaration cease for good?
"Will the Independent Monitoring Commission progressively report that that is the case over a sustained period of time?"
They must then be clear about the future relationship between the Provisional movement and the PSNI. He asked would they make clear their "complete regard for the rule of law in both jurisdictions?"
He said the Provisional movement was a conservative one, reflected in the slowness with which they had dealt with these issues. It was the SDLP, he said, which had been "daring and courageous" in endorsing policing in Northern Ireland and agreeing to serve on the Policing Board. "The SDLP took a huge political risk, and by their skill and determination have made a major contribution to the peace process."
He said there seemed to be some within republicanism who wondered whether a deal with unionism was either possible or desirable, and who may think that the real deal can only be done directly with the British government. "Some recent statements from Sinn Féin would seem to indicate such a perspective.
"I believe that any such narrow strategy is gravely mistaken. The true objective of Irish republicanism has to be a local political relationship with unionism, based on mutual respect and on the principles set out in the Good Friday agreement."
Direct rule from Westminster would "never complete the transformation in relationships between the two communities that is necessary to help normalise society in Northern Ireland".
Turning to unionism, he said that if the Provisional movement provided what was required, "the political leadership of unionism - now held by the DUP - must reciprocate in a meaningful and substantive way. The Irish Government will expect the DUP to commit itself to inclusive power-sharing within the Assembly and the Executive and to fully work the North/South institutions of the agreement."
He said the proposals published by the Irish and British governments after the failed talks last December "provided a basis on which the DUP was willing to participate in the institutions. These proposals, which were consistent with the fundamentals of the agreement, included participation in an inclusive executive.
"Several of the parties may in the coming months wish to revisit aspects of these proposals. We will listen carefully to their views.
"However, insofar as the Irish Government is concerned, the principle of inclusion - and the mechanisms used to achieve it - remains an essential element of the overall political architecture." Mr Ahern said the DUP was fundamentally "a devolutionist party" and capable of making a power-sharing accommodation with nationalism.
