IRA Supplied Russian Surface-to-Air Missile to Spanish Terrorists

The Irish Republican Army, who are nothing more than a group of psychotic baby-killers, supplied a Soviet-made SAM (Surface-to-Air Missile) to Basque Separatist (terrorist) group ETA:

An attempt to shoot down the Spanish Prime Minister's plane by a Basque terror group failed when the missile supplied by the IRA did not work.
Three times in 2001 Basque separatist group ETA tried to destroy Prime Minister Jose Maria Aznar's presidential jet, but each time the Russian-made SAM-7 missile refused to work.
A suspected ETA member arrested earlier this month told Spanish investigators that the Strela missile system, which homes in on a jet's exhaust, was aimed at the Prime Minister's Dassault Falcon 900 executive jet when he visited the Basque country during a regional election campaign.
But each time, twice at an airport near the coastal resort of San Sebastian and once at an aerodrome near the Basque capital Vitoria, the weapon failed to launch.
Documents seized at the suspect's home in the Basque town of Lizartza at the time of his arrest reportedly show the faulty missile launcher was supplied by the IRA.
A letter, written in English, was sent to members of the IRA complaining about the sale of the defective SAM-7 to ETA.

What I don't understand is why anyone wants to confer any credibility or consideration on Sinn Fein/IRA whatsoever. The only place they belong is in a cell at Guantanamo.
