This expains what a Islamic Caliphate is all about. They take non Muslim's hostage and hold them for ransom and sell them into slavery. Other races and religions are slaves in thier world.

This is the way the world was for thousands of years and this is the way Radical Islamist beleive thhe world is suppose to be. For centuries Muslims sent armies through out Africa and sacked villages and marched the inhabitants back to ports cities and sold them into slavery to whoever wanted them.
