Al-Qaeda's leader Mustafa Abu al-Yazid believed to be dead.

When I saw this story, I wondered if perhaps it's a lead in to the capture and/or kill of OBL. I know many think he's probably already dead, me included, but if this administration was able to kill HIM, it sure would gain a lot of support for Obama.

I believe that Yazid has been killed because Al Qaeda announced his death.

As regards #3 being killed before:

According to some reports, he was also al Qaeda's third-highest ranking officer. If so, then he is (by my count) the seventh individual identified by U.S. intelligence as al Qaeda's "No. 3" since 2001 who has been killed or captured. Being No. 3 is clearly a dangerous job. For its part, al Qaeda itself has never identified anyone as the third man in its chain of command, and most likely there is more than one individual, at any one time, who reports to Zawahiri and Osama bin Laden directly.

There will ALWAYS be a number 3!!!!! Get it?!

Lets pretend we killed every Al-Qaeda member,
and the war on terror was won. What do we do now
with all the amended laws and acts that encroach our
privacy. Something tells me that they will not be in any
rush to revise anything. Instead, they just keep enforcing.
You!! Yes You!! Will then be the terrorist.
Which number will you be?!
