Seven years after 9/11 the so-called war on terror led by the US has left thousands of American citizens dead as well as hundreds of thousands of Arab and Muslim citizens.

Much of the Middle East is now in turmoil and Osama Bin Laden remains at large, a man few people outside intelligence agencies had heard of prior to 2001.

In a special series America and al Qaeda, Marwan Bishara, Al Jazeera's senior political analyst, examines the effects of the momentous day and the logic of the US-led war on al Qaeda and how the organisation became a global phenomenon.

Marwan is joined by leading analysts as well as the former head of the Bin Laden unit of the CIA and a former head of the Pakistani intelligence service.
