I wouldn't say it's un-biased...as it does present a viewpoint that's somwhat counter to the Administration regarding the nature of the terrorist threat. Perhaps it's bias is that it's pragmatically biased.
Not that there isn't a threat, but how our perception has been manipulated...and how the Islamists have manipulated their people.
Hence the whole "nightmares" theme.
Interestingly enough, the substantial points echo much of what I read in the book "Imperial Hubris", written by the ex CIA Bin Laden analyst.
It's not liberal, but very critical of the Bush Administration. I could go on an anti-neocon rant here, but you could just as easily watch the videos
