Wazup,Tunisia-It was a common mistake back in the day but for one Al Qaeda operative it was one mistake too many, and he can blame it all on the Millennium.
Back then there was great confusion about when the new millennium began, with some celebrating on Dec 31 1999/Jan 1 2000 and others a year later.
The smart money people, backed up by astro-physicists, pointed out that There is no year "zero", so the first millennium started on January 1, 1 C.E. and thus the second millennium ended 1000 years after that on Dec 31 2000/Jan 1 2001. So when Wahoo Ali Unhuh, cheif astro-physcist for Al Qaeda was consulted way back in 2007 about which date was the correct date to commemorate the attacks of September 11, 2001, his off the cuff remark that "There is no year zero." meant that for years after, planning for the tenth anniversary of the organization's most successful operation would be off by a year.
When September 11th, 2011 came and went without incident, the western world breathed a sigh of relief, but for Al Qaeda and Mr. Unhuh it was a confusing time indeed. Mr. Unhuh, who by this time was training to become a suicide bomber, was confused that his new skills weren't put to use on that date, and Al Qaeda was wondering why their enemies seemed so relieved that the "ninth" anniversary had passed so peacefully.
Today Mr. Unhuh takes out the trash, sweeps the sidewalk and does other routine maintenance as needed around Al Qaeda headquarters, while chunks of his protege bask in the glory of a scaled-down attack earlier this month.
"Sometimes, when things are slow", Mr. Unhuh laments, "I lean on my broom while sweeping up chunks of him and think, "that could have been me!".
