Turkey planning military operation against Kurds in Syria?

Daily Beast:

Turkey’s President Recep Tayyip Erdogan is planning a military intervention into northern Syria to prevent Syrian Kurds from forming their own state there, despite concerns among his own generals and possible criticism from Washington and other NATO allies, according to reports in both pro- and anti-government media.

In a speech last Friday, Erdogan vowed that Turkey would not accept a move by Syrian Kurds to set up their own state in Syria following gains by Kurdish fighters against the so-called Islamic State, or ISIS, in recent weeks. “I am saying this to the whole world: We will never allow the establishment of a state on our southern border in the north of Syria,” Erdogan said. “We will continue our fight in that respect whatever the cost may be.” He accused Syrian Kurds of ethnic cleansing in Syrian areas under their control.

Following the speech, several news outlets reported that the president and Prime Minister Ahmet Davutoglu had decided to send the Turkish army into Syria, a hugely significant move by NATO’s second biggest fighting force after the U.S. military. Both the daily Yeni Safak, a mouthpiece of the government, and the newspaper Sozcu, which is among Erdogan’s fiercest critics, ran stories saying the Turkish Army had received orders to send soldiers over the border. Several other media had similar stories, all quoting unnamed sources in Ankara. There has been no official confirmation or denial by the government.

The government refused to comment on the reports. Foreign Minister Mevlut Cavusoglu said “the necessary statement” would be issued after a regular meeting of the National Security Council, which comprises the president, the government and military leaders, this Tuesday.

 So the Turks want to go to war against the only effective ally the US has in the fight with ISIL?  The US should tell the Turks in no uncertain terms that this would be unacceptable and that US forces will be used to stop such an attack.
