However, the chances of Erdogan complying with the US request are slim. Obama also also only wants the easternmost gateway into Turkey closed - he imagines the Islamists fighting Assad in the west and taking arms and money from Washington are 'moderate' and given they are also supported by Turkey will makes no moves to limit their terrorism.
Erdogan is now skating on very thin ice; the EU is reeling from his policy of actively pushing migrants into Greece, with Turkey's old ally France in particular grief at this betrayal, he's lost Russia's support and now the US has turned against him. The generals must surely now be taking quiet soundings from these international players as to the likelihood of sanctions and international opprobrium if they act to remove Erdogan. If they get an answer that a coup will mean a deal of disapproving noise but nothing concrete followed by a swift move to co-operation if Turkey both halts the migrant flow, takes the pressure from the Kurds and closes the border to ISIS then Erdogan's days are numbered.
Back on 6th October I wrote:
Make no mistake; Turkey and the KSA are our real enemies, and the real threats to peace. We need to pour money and troops into Greece to secure Europe's Eastern flank against Turkey, and give full support to Russia, Syria and the Kurds in blocking Turkey from the South. Only then will peace start to return to Iraq and Syria, and the tsunami of migrants into Europe actively facilitated by Turkey start to stem. Oh yes. We need to kick Turkey out of NATO.I stand by that statement. However, if Erdogan is replaced by a non-Islamist military government her place in NATO is not at risk.
