Not a chance -
Iran to hide UBL makes no sense for them - All it would assure is an immediate U.S. Military response (with the FULL backing of the American public) - This is the last thing Iran wants or needs -
Also, for UBL it doesn't fit his MO at all - to put him at the mercy of a Country which has a centralized Gov't -
Nope, UBL is where he has been for the past 3 1/2 years - Ekking out a survival in the one area US SOF aren't allowed to operate with autonomy (That is the PAK border region) -
As for Zarqawi, he is in Iraq and leading his thugs/killers - We will get him, but it has been damn frustrating -
Where do you think Al-Zawahiri is? With OBL?
You make the common mistake of assuming rational thought and behavior by the mullahs.
