One gets the strong impression that Turkey is covertly aiding and abetting the Islamic State murder machine. Reading the argument over support for the Kurdish fighters defending Kobani, and how 'porous' the Turkish border with the territory now controlled by ISIS/L is, one wonders what all those Turkish troops are actually there to prevent. I suspect their orders are not to stop ISIS/L, but to prevent any Kurdish fighters from escaping IS thugs.
The Turks have watched this tragedy unfold, and they have made no effort whatsoever to stop the steady flow of 'Jihadis' rushing to join ISIS/L. One can only speculate on how much in the form of weapons, munitions and 'materiel' for the fight is being supplied directly to the ISIS/L fighting machine by the Turkish Army and across this border. If I were a NATO Commander, I would be seriously looking at how much 'Intelligence' material I gave my Turkish 'Ally' about anything planned against ISIS/L.
Turkey does have a problem with this little war, one which will come back to bite them very, very hard I think. A large part of their reluctance to do anything to prevent the slaughter on their border is that the victims are, largely, Kurds. Roughly a quarter of the existing 'territorial area' of modern Turkey is populated by Kurds who have long cherished the desire to have their own 'nation state'. This would include the area of Iraq and the portion of Syria that includes two major cities - one of them Kobani - and the Turks have fought a long and very bloody campaign to prevent this. It now sticks in their collective craws, that their 'enemy', the Kurdish PKK, is the only force that seems to be having any success against ISIS/L. Should the Kurds win, the Turks will face a battle hardened, rearmed and very determined army of Kurds who will want their independence from an oppressive regime that is currently prepared to see their people sacrificed in order to prevent just this scenario from arising.
Both ways the Turks face a major problem here. If they aid the Kurds - as other NATO members are doing - they will have to address the political ambitions of their 'enemy within'. If they allow the Kurds to be defeated, and allow the genocide to go unpunished and unchecked that will follow, they will, within a short time, face the ISIS/L Jihad to include their country in the 'Caliphate'. If the Kurds win ... Well, I don't have to paint a picture.
One thing is very clear, Turkey faces a 'no-win' situation of their own manufacture, and now the only thing they can think of doing is to prevent the Kurds from winning. So the are covertly helping the 'enemy of my enemy' in the hope the venomous ISIS/L will not turn and bite them when their objectives in Syria and Iraq have been achieved.
If the rest of NATO and the world have any sense at all, they will not allow this to continue. And they will not allow ISIS/L or their supporters anywhere in the world, to continue, to receive arms, or to 'fade back into the crowd'. Those that wave the black flag of ISIS/L anywhere must be hauled into court and face the full penalty of the law for their support, encouragement and participation in mass murder, genocide and religious oppression. Make no mistake, if the ISIS/L win in Kobani, they will not stop there, and the Turks know it, but are paralysed by their fear of a Kurdish 'settlement'.
It will destroy them. Watch this space.
