A majority of Canadians believe U.S. foreign policy was one of the root causes that led to the Sept. 11, 2001 attacks
The poll suggests that 77 per cent of Quebecers polled primarily blame American foreign policy for the Sept. 11 attacks. The results suggest 57 per cent in Ontario hold a similar view.

I'd like to know what aspects of US foreign policy led to the attacks of 9/11?
