Mohsen Sazegara, who was a high-ranking Tehran official before turning against the government, has argued that Ahmadinejad does not control the Guards outside of Iran. "Not only the foreign ministry of Iran; even the president does not know what the Revolutionary Guards does outside of Iran. They directly report to the leader", he said, referring to Grand Ayatollah Ali Khamenei. Although Ali Khamenei is the ultimate person in charge of the Quds Force, George Bush did not mention him. According to Richard Clarke, "Quds force reports directly to the Supreme Ayatollah, through the commander-in-chief of the revolutionary guards."
