The Islamic State group controls a third of both Syria and Iraq, where it declared a caliphate governed by an extremely harsh interpretation of Shariah law and demanded the allegiance of the world’s Muslims. The Taliban, by contrast, are narrowly focused on Afghanistan and Pakistan, and some leaders have even responded to past peace overtures. (AP Photo/Reza Shirmohammadi, File)
