The relationship between Turkey and the Islamic State is clearly closer than the Turkish government would have us believe.
“ISIS claims first beheadings inside Turkey,” Arutz Sheva, November 2, 2015:
The Islamic State (ISIS) jihadist group on Sunday posted a video claiming responsibility for the beheadings of a Syrian anti-ISIS activist and his friend in southern Turkey last week.
The video posted online said ISIS “slaughtered” Ibrahim Abdul Qader, 20, and fellow media activist Fares Hamadi in Sanliurfa on Friday “after they conspired with the Crusaders against the Islamic State.”
Abdul Qader had been working with the Raqa is Being Slaughtered Silently (RBSS) activist group, which sheds light on ISIS atrocities in areas under jihadist control in Syria.
“May every apostate know that he will be slaughtered silently,” the video said, in an apparent reference to the group’s title.
The video then displayed a series of news reports about the RBSS group and its anti-ISIS activities.
It closed with amateur video footage of a man who appeared to be Hamadi, his throat slit. Abdul Qader’s body was not shown.
Abdul Qader and Hamadi’s bodies had been found at the latter’s home in Sanliurfa on Friday morning by another friend, according to RBSS member Abu Mohammad.
The group’s activists have been killed by ISIS inside Syria in the past, but this is the first time a member had been murdered outside the war-torn country, Abu Mohammad said.
Turkey has long been accused by Syrian opposition activists, Kurdish fighters and sometimes even Western partners of allowing ISIS members to slip back and forth across its 911-kilometer (566-mile) frontier with Syria.
It was also revealed in documents seized in July that Ankara cooperated with ISIS by taking part in ISIS’s cross-border black market oil sales….

This is plausible. It might have been done by local Turks who pledged their allegiance to the islamic state or by IS fighters who sneaked (or were willingly let in) into Turkey.

If this man who was beheaded was murdered by an ISIS thug then this bloodthirsty ruthless action was keeping consistent with malicious and murderous mindset of the jihadists of ISIS. For ISIS had posted an online video claiming they that they had “slaughtered” that man. This is not only keeping with ISIS mentality but it’s also keeping in line with the mentality that the Koran instruct Muslims to have. As this “holy book” of Islam teaches in 47:4. “Whenever you encounter the unbelievers strike off their heads until you make a great slaughter among them…” Well,ISIS sure engaged the Koranic teaching of having this man slaughtered by beheading . As those brutal and deadly jihad fiends also did to many other people. Moreover, the savages who compose ISIS are so extremely brutal, destructive and murdering that they are similar ,in character. to the heinous villains described in the Bible. Which reads “Their feet are swift to shed blood: Destruction and misery are their ways and the way of peace they have not known.” Romans 3:15-17. [K.J.V.]

The victims are Muslims who belong to the Syrian activist group “Raqa is Being Slaughtered Silently” (RBSS). On their website, they have this sentiment:
“ISIS tarnished the image of Islam and Muslims all over the world”
I.e., Islam and the vast majority of Muslims are just fine and dandy, and ISIS has nothing to do with Islam. I belong to another activist group, this one of Kuffar, called DPOMHATMIR (“Dont Pee On My Head And Tell Me It’s Raining”), founded by the great Judge Judy (Peace Be Upon Her)…

If Turkey slides into civil war through an accelerated attack on its secular political foundations then what happens to the country’s membership and participation within the NATO alliance?
