According to the US Counterterrorism Center (2016) between 87 and 92 percent of terrorist attack fatalities are Muslim. ISIS thinks infidels are enemies, but they believe Jews and Christians could live in their ideal caliphate as second-class citizens. They think that Muslims who are Sunni, however, have seen the light and refused it. Sunnis are, therefore, apostates, and deserve annihilation. Close to 90 percent of the Muslim world is Sunni.
