Look. The only reason this idea was floated about was because Rumsfeld was on the news circuit telling everyone that there was 'intelligence' stating that Osama bin Laden had massive underground bunkers carved into mountains. Listening to him tell it, you'd think that he was a nemesis of James Bond. Of course, we (well, most of us) have accepted that it was a fabrication. We just don't care. And of course, we will be fooled again. And again, and again, and again.
I know - it's been a while.
