The fact that Bin Laden is dead will not bring an end to Al-Qaeda. At least not right away. His second in command, Ayman Al-Zawahiri, is still out there and he has been the operations leader for a number of years. He is less charismatic within the Muslim world but is still a significant figure. Al-Qaeda is like a franchise and can be run by different leaders. In Yemen it is run by an American named Anwar al-Awlak. This branch is called Al-Qaeda in the Arabian Peninsula (AQAP) http://www.huffingtonpost.com/brian-levin-jd/osama-bin-laden-yemen_b_856287.html. No, Al-Qaeda will continue.
The killing of Osama Bin Laden will be a morale blow to the Al-Qaeda movement. His ideological views will be questioned as a way to bring change in the Islamic world. Maybe now more Muslims will look towards the Arab Spring as a way to bring about change and allow all Muslims to experience freedom and participate in democratic change.
