From the late 16th Century to the early 20th Century, Ottomans and Russia fought 12 wars, of which Ottomans only won two of them outright. Three were fought to draws, while Russia won all the rest.
Starting with the rise of the Safavid Empire in Iran in 1501, the Sunni Ottomans and Shia Safavids fought eleven bitter wars, of which the Ottomans won five.

Given that history, it's hard to imagine Turkey building alliances with Russia and Iran.
Yet that is exactly what appears to be happening.
Yesterday it was Turkey and Russia.

Turkey has called on Russia to carry out joint operations against Islamic State (IS) militants in Syria, after crucial talks between President Vladimir Putin and Turkish counterpart Recep Tayyip Erdogan aimed at ending the crisis.

Today it was Turkey and Iran.

At a joint news conference on Friday in Ankara, Turkish Foreign Minister Mevlut Cavusoglu and his Iranian counterpart, Mohammad Javad Zarif, said the two neighbouring nations have agreed to "keep closer contact" on the issue of the "territorial integrity of Syria".

Also yesterday, Turkey has decided to do the unforgiveable - go "off-dollar" (google translate)

Prime Minister Recep Tayyip Erdogan, revitalize Russia relations St. On his return visit to St. Petersburg, Putin's interview date it assessed the implications for Turkey. Erdogan stated that the positive results of the Let 's reach agreement, "of course will have positive repercussions. You know, the dollar fell below three. Only now it dropped below three dollars for the trip. We talked about something today. We said; So shopping is even more useful if we make the ruble and Turkish lira. It's a case such as dollar falls further. The currency printing, we can get rid of the currency printing.

Without a doubt, Turkey has gone "off script", so much so that NATO allies are starting to get nervous.
Turkey is edging away from NATO

Turkey may seek other options outside NATO for defense industry cooperation, although its first option is always cooperation with its NATO allies, Foreign Minister Mevlut Cavusoglu said on Thursday.

Consider these recent headlines.
Air Force relationships with Turkey a concern in wake of coup attempt

Erdogan also accused Army Gen. Joseph Votel, the head of U.S. Central Command, of "siding with coup plotters," a charge Votel denied

Why would Erdogan say that? Because coup planes took off from Incirlik.
Turkey Is No Longer a Reliable Ally

These days, however, the U.S. and Turkey see eye to eye on very little. The two countries are at odds over Syria and the urgency of removing Syrian President Bashar Assad; over support for Syrian Kurds who, in contrast to the Turks, have proved to be reliable U.S. partners in the fight against Islamic State; over the territorial sovereignty of Iraq; and over continuing sanctions on Iran.

Op-Ed Let's get our nuclear weapons out of Turkey

There are no do-overs in history, but there are lessons. The 1979 hostage crisis should have taught us the importance of proactively responding to obvious threats and removing vulnerable targets — a lesson that should be applied now if there are U.S. nuclear weapons based in Turkey.

EU rift with Turkey deepens

Austria has threatened to use its veto to block further talks on Turkish membership of the European Union, deepening the stand-off with Ankara over President Recep Tayyip Erdogan’s crackdown on democratic freedoms.
The move could jeopardise the EU’s controversial migrant deal. Turkey has already threatened to pull out of the agreement, potentially sending hundreds of thousands of asylum-seekers to Europe.

Does everyone see a pattern forming here?
The elites in the press and in Washington are taking this seriously, as well they should.
Without Turkey, overthrowing Assad will be nearly impossible.
Without Turkey, isolating and threatening Russia will be much harder.
Without Turkey, NATO stops at Europe.
Without Turkey, the U.S. Empire is put in a tough spot.

That's not to say Turkey can just reject its subordinate role without serious consequences.

The biggest threat from an escalation of conflict with the West would be a blow to Turkey's extremely fragile balance of payments.
Adding its $30bn current account deficit and $180bn foreign currency debt which comes due within a year, Turkey needs new foreign capital equal to roughly 28 percent of its GDP - one of the highest ratios among developing nations. That means it needs to borrow roughly $210bn a year to stay solvent.
That foreign capital comes almost entirely as loans, short-term bonds or "hot money", which is capital invested in Turkish lira denominated bonds and equities. And almost all of these funds originate from Western banks or funds.
