The leader, Abu Bakr al-Baghdadi, is destroying Shite mosques and holy places in territory his group controls. He is calling himself Caliph Ibrahim.
He is now the world's most wanted man.
I think his rule won't be long; only the most radical Sunnis and jihadists will support him.
An Iranian-supplied plane or a drone will end his roll.

Left behind, however, is the continuing Sunni-Shia split, just how the Iraqi lands will be divided, and whether a truce can be forged.
