The 9/11 Decade (3): The Clash of Civilizations?

In 1998, Osama bin Laden and Ayman Zawahiri declared war on the US, outlining a philosophy of the clash of civilizations which legitimised attacks on the West - both soldiers and civilians. In the US, a group of politicians who became known as the Neocons believed they too had a moral duty to change the world. Both groups found their opportunity in the attacks of 9/11 and the invasions of Afghanistan and Iraq.
