Why did Al Qaeda attack the US ?

Read Bin Laden’s Letter to America written in 2002.

Mostly it lists where Western governments had either directly persecuted Muslims or didn't oppose or stop persecution of Muslims.

Middle east countries have it rough. America tries to keep them destabilized, and if they try to evict Americans or fight back America is prepared to kill as much as twenty times as many of their people: mostly their women and children. It's the American way that America keeps Americans from reading about in the news.

According to the leader himself Bin Laden's big gripe with the US was their presence and meddling in Saudi Arabia. To be clear he turned on the Saudi government too for what he considered fraternization with the enemy.

So Larry Silverstein could build a building to his liking and guarantee it for another hundreds yrs for his family.

Typical middle child syndrome. He's like #26 out of 57 kids.

US Military we're in Saudi Arabia

America didn't learn it's lesson from 2/26/1993.

Bin laden was vulnerable from the air. USA should have got him after US Cole where 17 US sailors we're killed, US Embbassies in Mombasa and Nairobi we're bombed.
U S A should have more respect for it's soldiers/sailors then to send them into afGaNisTaN-.
USA is lead by madmen

Those who benefitted the most had the motive.
The response from America when the Bush family friends attacked was great for Rumsfeld and the Bush family, and the war business.

Read about the connection between Bush family and Bin Laden family way back 40 years ago (best friends) And how much bullshit is in all of these “terrorist attacks”. 9\11 an inside job,

Page 11 of the Taliban Membership Handbook. There are rules and guidelines to go by.

Because every time they took on the Israelis they got their butts kicked, needed a weaker opponent

Because they are stupid. I meanlook at the taliban!!

Bush

Perceptions of American imperialism, but they attack the West in general too as being "part of it."
