About 20%+ of Turkish population are Kurds. They are located mostly in the east
and south east. In the Syrian and Iraqi fighting the Kurds have been protected
and supported by Christians and other minorities. They have also been effective
whereas I suspect Turkey is more interested in putting down the Kurds more than
ISIS. It's a complicated deal, but I see Turkey as a poor ally.
Turkey still holds remnants of the old Turkish Empire. Southeastern Turkey has
a majority Kurdish population who by in large do not want to be part of Turkey.
France and the U K made a serious mistake after WWI when they put the Kurdish
lands in Syria, Iraq, Turkey, and Iran. The people living there now are paying
for those mistakes.
Erdagon is the next Assad. Turkey was a terrible ally to begin with. But with
Erdagon turning it into an authoritarian regime, they are moving toward the
hostile column. Sad but predictable. Turkey was always the place
that people pointed to as an example of a country where western freedoms could
coexist with an Islamic majority. Unfortunately, the inevitable has happened.
