The late Jack Holland and Henry MacDonald are to be commended for an authorative account of the emergence, campaign, spiral and collapse of Seamus Costello's IRSP/INLA. Costello, another in the long line whom left Official SF/Official IRA in the early 70s to set up the IRSP (The idea being a combination of Conolly-Inspired Socialist core values and Ulster Republican paramillitarism.) genuinely must have thought he was filling some kind of terrorist 'gap' in the market. (Given the lack of paramillitary presence on the part of the Officials, and the lack of Socialist principles on the part of the Provisionals.) Alas, all he did was set in train a tragic chain of infighting, assasinations, (Including his own in 1977.) internal kidnappings of party rivals, drug deals, post office and bank robberies, splits, and a vicious showdown with the Belfast Provisionals on Halloween 1991. (Which further split what remained of the INLA.) Part tragic, part shocking, part absurd, you will be amazed, when even after Costello's death, at how the organization still relentlessly carried on. Even if it meant spending more time threatening to kill its own members.)
Suffice to say, it's also a broad canvas in terms of its cast list. Eammon McCann almost joins the INLA, but decides not to, over his refusal to give a 'first option' on journalistic pieces to their in-house newspaper, 'The Starry plough'. Bernadette Devlin and Costello fall out over which one is the most socialist of the two. Patsy O'Hara and Mickey Devine starve themselves to death in the Maze, even though they're reviled and shunned by their Provisional counterparts. Airey Neave is assasinated in London by the INLA, only to see the Provisioanls deny them publicity by claiming responsibility for it. Gerald Steenson sees his attempts to portray himself as a would-be leader in waiting, lead to his demise. Dominic McGlinchey leaves the Provisionals to join the INLA, only to be shot dead in a phone box in front of his children by his former colleagues. All of which culminates in a 'Night of the Long Knives'- purge carried out by the Provisonals in 1991. Things would never be the same for the threadbare INLA ever again. Holland and MacDonald capture it all in painful detail. At the end, as befitting all Irish Republican terrorist organizations, all one is left with is a litany of vicous waste, fanaticism, death and pointlessness. As with the Provisonals, the Real IRA, Continuity IRA, and the New IRA, the INLA were their own worst victims. No true glory here.
