Turkish and Saudi fury that their allies Daesh / ISIS are now under severe pressure in Syria are leading both to reckless idiocy. The Turks are breaching international law and acting wholly against NATO remits in shelling Kurd positions in Syria; the Kurds are set to close the door between ISIS and Turkey through which Erdogan gets his family's illegal oil and sends Islamist fighters and supplies to ISIS.
KSA have sent both aircraft and ground troops to Turkey to bolster efforts to keep the ISIS border crossing open, but the head-chopping nutters face humiliation if Russia shoots down a western-made warplane or destroys a Saudi ground formation in Syria. Russia's options against mad dog Erdogan's Turkey are constrained by Turkey's NATO membership; any counterbattery fire against Turkish gunners would lead Erdogan to call for NATO support. The Saudis on the other hand can be destroyed without any such compunction, and it would severely embarrass the West if 'backward' Russian weapons systems succeeded in downing a sophisticated F15.
That both Turkey and KSA have thrown off all shackles of pretence in so openly and riskily giving backing to their ally Daesh / ISIS demonstrates the strength of their links to the Islamist scum. It also suggests a new understanding between the US and Russia not to allow the mad Sunni dogs to escalate the Islamic civil war into a wider conflict. After doing all they could to provoke a Russian / US incident, the two regional actors have finally been forced to act or see all their hopes of Sunni hegemony to be realised through Daesh / ISIS finished.
Both Turkey and KSA are making quite explicit their true war aims - which have nothing to do with fighting their Sunni ally, Daesh / ISIS
From the Indie, quoting the primitive savages' 'Foreign Minister' - "Bashar al-Assad will leave - have no doubt about it. He will either leave by a political process or he will be removed by force."
And from RT:- Turkey ‘won’t allow’ Azaz, northern Syria, to fall to Kurdish militia, promises ‘harsh response’
Their ISIS ally must feel buoyed today by such open support ..
