ISIS: The Latest Phase of the Jihad

The best way to understand the Islamic State (ISIS) is to see it as the next phase of al-Qaeda. All Sunni Islamic jihadi groups—Boko Haram, ISIS, Taliban, al-Shabaab, al-Qaeda, even Hamas—share the same motivations based on a literal and orthodox reading of Islamic history and doctrine: resurrecting a caliphate (which existed in various forms from 632 to 1924) that implements and spreads the totality of sharia, or Islamic law.
