Captain Ed has an excellent series that shows that Richard Clarke’s claims that terrorism and al-Qaeda were the Clinton Administration’s top concern isn’t remotely true. (The first part is here, followed by part two, and a third part.)
As he notices in the Clinton report, there is no mention of al-Qaeda and Osama bin Laden is only mentioned four times – and never as the major priority that Clarke claimed he was.
Clarke’s credibility is roughly zero at this point – it’s clear he’s towing the Clinton line to try and rehabilitate Clinton’s shattered “legacy” by altering the record to favor Clinton. However, for all his spinning, he can’t ignore that there’s absolutely no substantive evidence to prove it.
