That reads as though you think 9/11 was some inexplicable act of random aggression, coming out of nowhere. From other things you've written over a long period, I know you're very aware of all sorts of grievances against decades of western interference in countries in the Middle East, including installing corrupt and pliant regimes, setting up US military bases, and exploiting local natural resources (usually in conjunction with whichever corrupt regime the US has supported). It's resentment of the actions the West has taken over decades that's the issue, not some kind of blind hatred of anyone who's different.
I think you're massively understating the role of religion in this. As the poster said on the previous page, by far the biggest number of casualties have been people in the Middle-Eastern countries themselves, usually for minor variations in the way they worship the same sky fairy.
Yep including one today in that Pakistani school. How about the actions of Boko Haram? Don't think they've attacked any western targets but are wreaking havoc in Nigeria.
Fair enough attributing the terror threats here and in the US and Aus to anger over the West's actions but it does only make up a tiny portion of the violence carried out by these organisations.
