Why did Muslims attack the twin towers?
"As Allah is my witness, we had not considered attacking the towers, but things reached the breaking point when we witnessed the injustice and tyranny of the American-Israeli coalition against our people in Palestine and Lebanon; then I got this idea" ,Osama bin Laden, video "Message to American people" broadcast 29/10/2004 by al Jazeera, translated and transcribed by the broadcaster. Over the years, bin Laden gave various reasons both vague and precise for waging war on the West, but in that video he did give a reason, if a broad one, for that particular attack.
