And Syria? Druze, Alawite, Shia, Sunni, Orthodox (Greek, Armenian), Catholics (Armenian, Greek), RC, Baha'is, Jews, Chaldeans, Maronites, etc, etc.
It made Yugoslavia look like amateurs.
The reality of what happened recently in both Iraq and Syria is that a form of ethnic/religious cleansing was 'allowed' to occur. The vast majority of Christians that resided in Iraq prior to 2001 have already fled the country, further weakening the position of those remaining behind. Syria will be the same for certain. Lebanon has been bleeding Christian emigrees since the mid 1970s. This process will continue around the Middle East, it will continue in places like India (higher percentage of Indian immigrants to the west tend to be Christians or Sikhs). How many Jews left the old Soviet Union when the opportunity presented itself? Vast majority were economic immigrants initially but the 'want' to go to a place where they 'belonged' or were a part of the majority played a significant part.
