The Good Old Provisional IRA

In 1991, on the 75th anniversary of the Easter Rising of 1916, Gerry Adams pointed to the Proclamation in the Sinn Fein Press centre, and declared to journalist Suzanne Breen: 

"Would any of the men who signed that document have signed the Anglo-Irish Agreement? Would Tom Clarke have extradited Dessie Ellis?

No way would those people be involved in talks about talks, rolling devolution, Atkins’ round-table conferences and the whole litany of Sunningdale-Darlington."

The IRA proclaimed itself "the lawful and legal" government of Ireland,why does it reject the standards and responsibilities of a moderngovernment?

The IRA Green Book was in existence while the IRA, (1956 edition), and the PIRA, (1977 edition) waged their armed stuggle. The Green Book said:

"Commitment to the Republican Movement is the firm belief that its struggle both military and political is morally justified, that war is morally justified and that the Army is the direct representative of the 1918 Dail Eireann Parliament, and that as such they are the legal and lawful government of the Irish Republic, which has the moral right to pass laws for, and to claim jurisdiction over the territory, air space, mineral resources, means of production, distribution and exchange and all of its people regardless of creed or loyalty."
