There seems to be controversy about whether Turkey is an ally of ISIS (or IS or ISIL or WTF ever they call themselves) or not. I did a brief review of articles from several sources….and found a few articles giving opinions on the issue. I am not an expert on the issue, but I have included articles from different publications, from 2014 and 2015.
I tried not to cherry pick headlines which just represent the theme that
Turkey is actually an ally of ISIS, or at the very least, that Turkey is not a friend of the Kurds, a group who ARE actively warring against ISIS within Syria.
All of this said…I am no expert, and leave the reader to decide what the truth is based on taking all articles in balance.
