Sounds like CBN only talks to other evangelicals —the few that exist among Iraqi Christians. ISIS will kill all Christians regardless of denomination—on the other hand Assyrian-Chaldean & Armenian Christians might be welcomed into Iran where they have communities. For all their lousiness—Iranians tolerate these Christians because they don’t try and proselytize. Their services are not in Farsi. thus no threat to Islamic theocracy.
They are more than capable of moving on to that as their goal is a throughly ‘purified’ form of Islam. For the moment there are lots of hated Shia and backsliding Sunnis to kill.
