Is Turkey more trouble to NATO than it is worth?

The received wisdom is that Russia’s invasion of Ukraine has breathed new life, and a new sense of purpose, urgency and unity into nato. Someone forgot to tell Recep Tayyip Erdogan. Over the past month the Turkish president has blocked nato enlargement, warned of a new offensive against American-backed Kurdish fighters in Syria and stoked tensions with Greece, also a member of the alliance. A few pundits, in the West but also in Turkey, are once again debating whether nato and Turkey should part ways. This time, they are not alone. “Leaving nato should be put on the agenda as an alternative,” Devlet Bahceli, leader of a nationalist party in Mr Erdogan’s coalition, recently said. “We did not exist because of nato and we will not perish without nato.”

Frustration is also mounting in Western capitals, and in Kyiv, over Turkey’s willingness to accommodate Russia. Many in those places had hoped that the war in Ukraine would force Mr Erdogan to reconsider his romance with Vladimir Putin, Russia’s president. Opportunism has prevailed instead. Turkey has sold armed drones to Ukraine and closed access to the Black Sea for Russian warships, but it opposes Western sanctions against Russia and openly courts Russian capital. According to a report in the Turkish media, dozens of Russian companies, including Gazprom, are planning to move their European headquarters to Turkey.
