Sis is a group that has a clear political objective. it wants to rid the middle east of western values and modern laws and bring back a way of life that it considers authentically . it wants to erase national borders of the middle east and unite all muslim-dominated nations under a where sharia will be imposed and respected.

ISIS is a terrorist organization that mostly operates in the Middle East and Northern Africa, though it has its members and supporters in Western Europe, the Balkans, Central Asia, and the Caucasus regions. This organization leads itself by literary accepting the Koran and what it says and obliges the Muslims to believe in and how to act. That is also fueled up by extremist religious preachers and political figures. Their goal is to establish Sharia law all over the Muslim world, and to convert everyone to Islam in those territories. Also, they want to eradicate the Western values and influence as they see them as evil, incompetent, sinful etc. According to them, all of the Muslim world should be united in a single Caliphate, and everyone in it should live literary as the Koran says. That doesn't stop there though, as the organization has in mind that it has to spread the Islam all over the world, implement Sharia law, and be the only religion in the world. In order to achieve this, this organization committed pretty much all violations against the humanity, with millions of displaced, murdered, injured, kidnapped, performed genocides etc. Luckily big portion of this organization has been destroyed lately, so only small fragments of it exist.
