Many of the Iraqi christians fled to Syria, which is why the number of christians there is increasing. Coupled to that is the FACT that Assad protected and protects Christians
That's another of my bugbears, instead of supporting Assad obama went to support the jihadis
We should set up a a Christian lebanon, Christian southern Syria, Alawite coastal syria, Kurdistan and renewed Assyria.
It is more than that. Conversions are taking places. Some would have long ago, but for fear of laws against it. Efrin had more than one Christian Church. Kobani has one. Many communities further East are majority.
