Turkey is a NATO member that bought Russian air defense systems. It condemned Russia's invasion of Ukraine while refusing to join Western sanctions. It mediates between Kyiv and Moscow while selling armed drones to Ukraine. It blocked Sweden's NATO membership for nearly two years, then approved it in exchange for concessions. It hosts American nuclear weapons at Incirlik Air Base while threatening to expel American forces.
To Western analysts, this looks like inconsistency. To Erdoğan, it is a carefully executed strategy. Turkey has spent the last decade transforming from a predictable Western ally into something far more valuable and far more frustrating: the world's most consequential swing state.
The Geography of Leverage
Turkey controls the Bosphorus and Dardanelles straits — the only maritime passage between the Black Sea and the Mediterranean. Under the 1936 Montreux Convention, Turkey regulates naval transit. When Russia invaded Ukraine, Turkey invoked Montreux to block warships from non-Black Sea nations — a decision that limited NATO's ability to support Ukraine by sea while also limiting Russia's naval reinforcement. Both sides had reason to keep Turkey cooperative.
Turkey borders eight countries across Europe, the Middle East, Central Asia, and the Caucasus simultaneously. No other country occupies this many strategic intersections. This geography is not Erdoğan's creation. But he has turned it into leverage in a way his predecessors did not.
The NATO Relationship
Turkey joined NATO in 1952 and for decades was a reliable ally. The relationship began fraying after the 2003 Iraq War, when Turkey's parliament refused to allow American forces to use Turkish territory for the invasion. The real break came with the 2016 coup attempt. Erdoğan blamed American-based cleric Fethullah Gülen. The United States refused to extradite him, and Erdoğan never forgave them.
The S-400 purchase followed in 2017 — Russia's air defense system, incompatible with NATO architecture, potentially giving Russia intelligence on NATO air operations. The US expelled Turkey from the F-35 program. Turkey threatened to close Incirlik. The relationship has been in managed dysfunction ever since.
The Erdoğan Doctrine
Erdoğan's foreign policy rests on "strategic autonomy" — Turkey should not be subordinate to any single power but should maintain relationships with all major powers and extract maximum benefit from each. What makes Turkey's version distinctive is the combination of genuine leverage and genuine willingness to use it loudly, publicly, and with evident relish.
Turkey has turned geography into leverage, refugees into bargaining chips, and ambiguity into a foreign policy.
The Refugee Card
Turkey hosts approximately 3.6 million registered Syrian refugees plus hundreds of thousands of others. The 2016 EU-Turkey deal outsourced Europe's refugee problem to Erdoğan in exchange for six billion euros in aid and visa liberalization. When the relationship with Europe sours, Turkey opens the border. When it needs concessions, it threatens to. Europe, terrified of another 2015-style crisis, has been paying Erdoğan not to destabilize it ever since.
The Economic Dimension
Turkey's strategic maneuvering happens against a backdrop of serious economic difficulty. Years of unorthodox monetary policy — Erdoğan's belief that high interest rates cause inflation, opposite to standard economic theory — produced currency collapse and inflation above 80%. The lira has lost the vast majority of its value over the past decade. This economic vulnerability constrains Turkey's ambitions and creates domestic political pressure that complicates foreign policy.
The Bottom Line
Turkey is not an unreliable ally. It is a rational actor pursuing its interests with unusual clarity and skill. Erdoğan has positioned Turkey as indispensable: too important to expel from NATO, too difficult to ignore, too strategically located to alienate.
Whether this is sustainable is a different question. As the US-Russia and US-China confrontations deepen, the space for Turkey's middle position narrows. At some point, everyone gets asked to choose a side. Erdoğan has spent a decade avoiding that moment. He won't be able to avoid it forever.
