why 9-11 happened? This is partially a rhetorical question because I have my own theory, but am interested in others.
Note: Mods, if those conspiracy theorists rock along to this thread can you give them the boot? I think they have enough threads to talk about their blather...
I'll start off by saying that I'm not a Truther. I fully believe that September 11th was masterminded by KSM and OBL.
I do, on the other hand, believe there was a catastrophic information failure on the part of the US intelligence community. But as to the root reasons why - there are many.
This is less a list of why we were attacked, and more a list of the justifications that Al Qaeda used to make the attacks acceptable to their followers.
1. Israel. Without getting into the history of the Arab-Israeli conflict, it has become the equivalent of what "Communism" was to the US in the 50s. Just like the boogeyman of Communism was used to justify going to war all around the globe, the US support of Israel is a factor in why we were attacked.
2. General Meddling. Aside from Israel, it should surprise no one that a whole lot of people around the world don't believe that we know what's best for the world. Therefore, when we go around the globe meddling in elections, governments, and arms deals, we make enemies. It's a fact.
