Via the Irish Examiner:
Details of the plan emerged in a letter from American al Qaeda spokesman Adam Gadahn to an unidentified recipient. The correspondence was found in the house in Pakistan where al Qaeda leader Osama Bin Laden was shot dead by US forces last year.
"This was after I noticed the sympathy of the Irish people to the Palestinian issue, and the soft treatment by the Irish judicial system of the Muslims accused of terrorism, and also not participating with its troops in Bush’s crusade wars.
"Also, what helped to prepare the message was the last economic crisis that affected Ireland a lot, thus forcing its youth to look for sources of living in the outside. The other matter is the increasing anger in Ireland towards the Catholic Church after exposing a number of sex scandals and others. The people there are moving towards secularism, after it was the most religious of atheist Europe, and why do not we face them with Islam?"
The letter was written in late Jan 2011.
And via the Irish Times: "Catholics were historically the prominent enemies of the Jews, amongst the other Christians. They were also the original enemies to the Evangelist Protestant who were the vanguard of the Crusades.”
