In the back of my mind, perhaps because of the stories about the "anti-war" protestors attacking the US plane in Ireland, there's also a warning bell going off about the IRA. Their particular expertise I believe is explosives. I don't see enough in these stories to prove it, but I suspect the IRA is cooperating with the muslim terrorists again.
Given the extent to which the IRA depends on donations from Irish-Americans, that would be a very foolish move.
