@kheredia I think retaliation is a real probability. I do think they felt they had good reason, but if purposefully killing civilians is justifiable to you, you can certainly volunteer your life in payment for any mistakes you think have been made by others.
This is the reason OBL gave, “Allah knows it did not cross our minds to attack the towers but after the situation became unbearable and we witnessed the injustice and tyranny of the American-Israeli alliance against our people in Palestine and Lebanon, I thought about it. And the events that affected me directly were that of 1982 and the events that followed – when America allowed the Israelis to invade Lebanon, helped by the U.S. Sixth Fleet. As I watched the destroyed towers in Lebanon, it occurred to me punish the unjust the same way (and) to destroy towers in America so it could taste some of what we are tasting and to stop killing our children and women.”– Osama bin Laden, 2004
Nineteen years passed between what is stated to be inciting event and the event. I do not disagree that the US has made some bad policy decisions, but really… nineteen years. An eye for an eye, it continues the cycle of violence. The first attempt in 1993 was a failure of mission but a political statement; there was not a massive manhunt and war started.
Was America supposed to say, “Yeah, you are right. We deserved that in 2001. Please continue to kill Americans until you feel retribution has been achieved.”
In 1998 OBL signed a fatawa, ”... [t]he ruling to kill the Americans and their allies civilians and military – is an individual duty for every Muslim who can do it in any country in which it is possible to do it, in order to liberate the al-Aqsa Mosque (in Jerusalem) and the holy mosque (in Makka) from their grip, and in order for their armies to move out of all the lands of Islam, defeated and unable to threaten any Muslim. This is in accordance with the words of Almighty Allah, ‘and fight the pagans all together as they fight you all together,’ and ‘fight them until there is no more tumult or oppression, and there prevail justice and faith in Allah’” This does not sound like someone on a mission for justice.
