Al-Qaeda doesn't exist. It's a made up organization by the US government to give a name to the face of terrorism. What does exist are separate terrorist sects, that sometimes work together, but more often than not work apart.
Wrong. While there are many terrorist sects, al Qaeda is most definitely a real organization. You might want to read a book called, "The Looming Tower." Pretty good read. Traces al Qaeda from its earliest pre-al Qaeda beginnings with Sayid Qtub as the head honcho.
