accumulated goodwill for him," said one celebrity journalist on CNN. Both U.S. Secretary of Defense Robert Gates and Chairman of the Joint Chiefs of Staff Mike Mullen maintain that the delay didn't signal any kind of dispute within al-Qaeda, and Mullen reiterated U.S. death threats toward al-Zawahiri. According to US officials within the Obama administration and Robert Gates, al-Zawahiri would find the leadership difficult as, while intelligent, he lacks combat experience and the charisma of Osama bin Laden. Activities in Iran Al-Zawahiri allegedly worked with the Islamic Republic of Iran on behalf of al-Qaeda. Author Lawrence Wright reports that EIJ operative Ali Mohammed "told the FBI that al-Jihad had planned a coup in Egypt in 1990."

On the seventh anniversary of the attacks of September 11, 2001, al-Zawahiri released a 90-minute tape in which he blasted "the guardian of Muslims in Tehran" for recognizing "the two hireling governments" in Iraq and Afghanistan.
