As far as Ireland goes it would appear that Richard and Christmas are talking about two different periods in history.
Richard thought that Christmas was referring to 1969 - 2008, whereas Christmas was talking about 1916 - 1921. Neither comparison is relevant to the Caliphate or the Islamic State.
Tell me Christmas, what has been the response to Abu Bakr Al-Baghdadi's appeal for all Muslims to flock to his newly established "country"? As far as I can see most people do their level best to flee any territory threatened by this wanker and his "forces". Unfortunately IS, who to date have not fought against any rated opposition and who are apparently fleeing the fighting in Syria, are about to come up against the Kurds backed by the best and most experienced air force in the world, it will be an experience that they will not enjoy.
