<<In the estimation of Al Queda there are 4000 less Jahadis willing to travel and fight because of Iraq.>>
These are jihadis killed in Iraq who won't be coming to America because they're dead or jihadis tied down in Iraq and too busy over there to come over here?
4000 dead by their own estimate , I would have guessed higher.
The number of Al Quieda alive and busy in Iraq would just be a guess , but I would guess it to be less than 10,000.
