The extremist group that is threatening the existence of the Iraqi state was built and grown for years with the help of elite donors from American supposed allies in the Persian Gulf region. There, the threat of Iran, Assad, and the Sunni-Shiite sectarian war trumps the U.S. goal of stability and moderation in the region.
But in the years they were getting started, a key component of ISISís support came from wealthy individuals in the Arab Gulf States of Kuwait, Qatar and Saudi Arabia. Sometimes the support came with the tacit nod of approval from those regimes; often, it took advantage of poor money laundering protections in those states, according to officials, experts, and leaders of the Syrian opposition, which is fighting ISIS as well as the regime.
