I too have seen many of the arguments for and against the 9/11 conspiracy, but there is another angle to this thing. 

 America got a black eye. Either it was a Neo-con plot or truly the act of Osama and crew...it was 8 years ago, and we are still spending precious lives and resources just to settle the score...

 My advice to America is no matter what happened, get over it. Now, not to be confused with "forgetting", because yeah--never forget--but we are falling right into what the perpetrators wanted.

 For example, the tragedy at Mt. Hood this week was terrible, but the Conservative suggestion that we should halt the health care vote because of the act of a deranged asshole...you are letting one hateful act cripple your entire country. This is what terrorism looks like when it works. You pop someone stronger than you, get them angry and paranoid, and their daily activities are slowed or stopped. I think the bigger issue is why we haven't rebuilt the towers, why we can't say alright, some asshole punked us, lets move on...

 Please, I'm not suggesting that we don't fight terrorism with military force, but ultimately, what causes terrorism isn't bad guys in caves, but rather poverty, desperation, and the image of great and terrible power in the eyes of the hopeless. Osama couldn't convince me to kill myself to prove a political point...I've got way too much to live for. However, take away my home, my food supply, make my world brutal and ugly...who knows what I might do. If you want to stop terrorism, you have to work on healing the ties between people, and fixing our image in the world. That way, when someone says America is the Great Satan, more folks would be less inclined to believe it.
