Saudi Arabia started to finance terrorists since the 2003 Iraq invasion but from the onset of Islamic rebellion in Syria, Riyadh intensified its military and financial support to terrorist organizations like Al-Qaeda. The Islamic State of Iraq and Syria (ISIS), now threatening Baghdad, was funded for years by wealthy sheikhs in Kuwait, Qatar, and Saudi Arabia, three U.S. allies that have dual agendas in the war on terror. The extremist group that is threatening the existence of the Iraqi state and destroying neighboring Syria was built and grown for years with the help of elite donors from American supposed allies in the Persian Gulf region. Meanwhile the interrogation of a trusted messenger for the insurgent Islamic State of Iraq and Syria, or ISIS, led Iraqi commanders to a treasure trove of information on the terror group and its staggering $152 billion in finances. "He said to us, 'You don't realize what you have done,'" an intelligence official quoted the courier as saying two days before Iraq's second-largest city, Mosul, fell to ISIS. "Then he said: 'Mosul will be an inferno this week.'" The information – unlocked with 160 computer flash sticks – included names of fighters and commanders, code words, initials of sources inside ministries, phone numbers, emails and an extraordinary accounting of its rich war bank. "We were all amazed, and so were the Americans," the official told the press. "None of us had known most of this information." "Before Mosul, their total cash and assets were $875 million," the official added. "Afterwards, with the money they robbed from banks and the value of the military supplies they looted, they could add another $9 billion to that."
