Despite Bill Clinton's angry protestations, the bulk of the blame for America's failure to catch or kill Osama bin Laden lies squarely on the Clinton administration, at least according to CBS News terrorism analyst Michael Scheuer:
The former president seems to be able to deny facts with impugnity. Bin Laden is alive today because Mr. Clinton, Mr. Sandy Berger, and Mr. Richard Clarke refused to kill him...there's plenty of blame to go around, sir, but the fact of the matter is that the Bush Administration had one chance that they botched, and the Clinton Administration had eight to ten chances that they refused to try...it's just, it's an incredible kind of situation for the American people over the weekend to hear their former president mislead them.
Scheuer, by the way, was also a member of the Clinton administration:
Scheuer [was] the senior intelligence analyst who created and advised a secret CIA unit for tracking and eliminating bin Laden since 1996.
