A small army of fanatical Jihadists sieged 15,000 sq. miles of territory and shocked the world with it’s violence and brutality. The so called Islamic State is a terror organisation, the likes of which we have never seen before, having now amassed a huge army that rules over 8,000,000 people.

Terror has been at the heart of the Islamic States’s blueprint, mapped out in a most unlikely place, US detention camps set up to house prisoners of the Iraq war. Their master plan was a potent mix of religious fanaticism and violence and in this episode of This World by the BBC we see how they have managed to accumulate such wealth, further enabling their grab for power in the region.
