Islamic State (IS) (also known as Islamic State of Iraq and Syria (ISIS) or 'Islamic State of Iraq and the Levant' (ISIL), as referred by Barack Obama or 'Daesh', as referred by John Kerry), is a terrorist organization that operates in Iraq and Syria. Founded by Abu Musab al-Zarqawi, it grew out of al Qaeda in Iraq. It was founded during the Operation Iraqi Freedom of 2003. Its current leader is Abu Bakr al-Baghdadi. IS currently fights non-Muslims, Shiite Muslims, the Iraqi Army and Kurdish Peshmerga troops. The goal of IS is to construct an Islamic Caliphate in Syria and Iraq.
Ramzan Kadyrov, (Chechnya), 38, said the U.S. secretly controls the Islamic State.  Documents obtained by a FOIA request of Judicial Watch show as early as 2012, U.S. intelligence predicted the rise of the Islamic State and the report envisions the terror group as a U.S. strategic asset in the fight against Bashar al-Assad.  VP Joe Biden admitted in 2014 that Saudi Arabia, the UAE, Qatar and Turkey had funneled hundreds of millions of dollars to Islamist rebels in Syria. Biden was forced to retract that statement.  The U.S. did precisely the same thing in terms of supplying and facilitating the Syrian opposition. Obama had requested $500 million to train fighters opposed to ISIS. In August, the Pentagon announced it would defend those forces from attacks by the Syrian government. 
Turkey's president Erdogan has good relations with Barack Obama and they both support Assad's ouster from Syria. Turkey is a major transit point for both foreign fighters and weapons, which makes both presidents complicit in the failure to stop fighters from joining ISIS ranks.

In 2014 IS took control of the Iraqi cities of Fallujah and Mosul. Since then Christians in Mosul have to pay "Protection taxes" for their faith. In 2015 IS defeated Iraqi troops and seized the city of Ramadi. IS now controls all the border areas between Syria and Iraqi.
