Is Al Qaeda a fabrication by Washington?: "The Power of Nightmares"
I found this article on Al Jazeera about a BBC series claiming the fabrication of a World Terrorism Organization is more a Washington neo-con exaggeration than a actual entity. Being a pure skeptic, I looked at the BBC and discovered that there is a mini series discussing this very subject.
From the Review -
The BBC film does not doubt that Osama bin Laden has helped finance several groups, but it does challenge that the Bush administration, "led by a tight-knit cabal of Machiavellian neoconservatives, has seized upon the false image of a unified international terrorist threat to replace the expired Soviet empire in order to push a political agenda."

As much as we have been lied to over Iraq, you really have to wonder about other things we've been lied to about. More on this later.
