During the previously mentioned carving up of the middle east, the Kurds didn't even get a country - straight bordered or otherwise,
and they are "an ethnic group who have historically inhabited the mountainous areas to the south of Caucasus (Northern Zagros and Eastern Taurus mountain ranges), a geographical area collectively referred to as Kurdistan. Most Kurds speak an Indo-European language belonging to the Northwestern Iranian branch. Kurdistan is divided into 4 different parts which are in Turkey, Iraq, Iran, and Syria. Kurdish people have one of the longest ethnic histories in the middle east. Their lineage dates back to as early as 2400 BC, where they occupied the same lands as they do today. However many foreign invasions and immigrants shaped the face of the Kurdish people over time. Though Kurds had followed the teaching of Islam since an Arabic invasion in the 7th century, their culture remained distinctly different from all the others found around it."
Just one of the many factors involved in the 'mayhem', and don't forget Islamic extremists are murdering Muslims too.
It isn't simply a question of Muslims versus the Infidels, there is, and always was, a great power struggle being played out right across the region.
