Nothing good will. I do not understand how for so many centuries, the Christian community could live in Syria. Or the early Muslims were more peaceful? In any case, it will be hard to live because peace in the middle East will not be a very long time.
Christians have been living in the middle east even before prophet Mohammed began spreading Islam. Syria was like 30% Christian a century ago. Now this percentage has gone below 10%. Lebanon was 70% Christian in 1930. Now it has been decreased to 30%.
The entire middle East is Muslim. If you don't count Israel. I think that every year Christians will be less until will not do. This objectively. Unless of course Christians will not create its autonomy, but then they suffer the fate of Israel.
