ISIS playbook

"Most Sunnis reject ISIS's brutality, its imposition of ultra-puritanical Islamic laws, and the fact that perhaps a third of its 12,000-odd fighters is made up of foreigners." "The latest ISIS yearbook, a document not unlike a corporate report, details no fewer than 9,540 attacks, including 1,083 assassinations, in Iraq alone last year, not including its operations in Syria." "Jihad against the awful regime of President Bashar Assad has attracted a flood of proclaimed holy warriors from across the world, including France and Britain. Cash has gushed from private donors in the Gulf, eager to help what they see as a noble cause, as well as from the ransoming of hostages."
