I think now would be a good time to bring up the HUGE errors in your sources. I wrote my high school thesis paper about this subject a few years ago, although it was about preventing terrorism through economics, not whether al-Qaeda exists not not.

al-Qaeda, or "the Base" in Arabic, is a decentralized organization. Osama bin Laden started it, but that doesn't mean he's always in control. Most members are self-identified, and have no idea what's going on with the other people involved. That being said, your sources are EXTREMELY flawed.

Firstly, I don't think the dictators of Islamist countries are the best sources of intellegence on an Islamist terrorist network. These are the same guys that say Israel doesn't exist, or that the Holocaust never happened.

Pravda is a notoriously unreliable source of information. They also claim that space aliens exist. They are basically the Russian Weekly World News.

I've read "The Power of Nightmares" and you are misrepresenting the book. It doesn't claim that there is no al-Qaeda, it just explains that al-Qaeda is not a highly organized, centralized network. You are also misrepresenting Ian Blair in the same way.

Jemaah Islamiya definitely exists, and it is far more centralized than al-Qaeda. Interestingly enough, the organization was one of the first to set up relief efforts in Pakistan after that earthquake.

Johan Galtung seems interesting, although since I can't read whatever language that's in, it would be nice if you posted an English language link.
