It could be Psy-Ops and a fake. Glad it got distributed around the globe either way, slows AQ recruits and allows us to keep killing the enemy without mercy.
And if so, that is even better news.
Beginning this war with the PC-impaired Clinton CIA and FBI, the current administration has been hampered by a profound lack of knowledge of the enemy and a dearth of assets to fight on the much more pivotal psychological battlefield.
If it is a fake, the intensity of the denials should tell us our enemy is afraid that it will be believed by the audience in this macabre play.
If it was written by someone in our own camp, then I say FINALLY we see the willingness and ability to fight in this manner.
Let's face it, the jihadis are losing in Iraq precisely because of Zarqawi's inability to see his brutality as counter-productive. Why would WE attempt to awaken him?
Look for Zawahiri to disavow the missive; his denial will be just as destructive to the enemy effort, as his very good advice to Zarqawi may go unheeded as a result. Either way, fake or not, the damage to the jihad is done.
