“This decision is a watershed in the history of Northern Ireland, and also addresses one of the critical challenges of post-conflict peacebuilding – specifically, control over and the disposal of weapons,” a spokesman for Mr. Annan said in a statement released at UN Headquarters in New York.”The Secretary-General calls on all parties concerned to seize this unique opportunity to consolidate the Good Friday Agreement further, and on those who had left the process to re-enter Northern Ireland’s devolved government,” the statement said.
