The most embarrassing of Putin’s failures since February is the mooted expansion of Nato to include Sweden and Finland. It is the exact opposite of what he was wanting to achieve by invading Ukraine, and impossible to hide from his own people. But Turkey’s President Erdogan is trying to prevent it happening.
Or is he?
The truth is more complex and more reassuring. Erdogan has a de facto veto over Nato expansion because it has to happen by consensus. In return for not using that veto he wants concessions on two fronts, while he walks a tightrope on a third.
Kurds. Erdogan’s public problem with Sweden and Finland joining Nato is that both give shelter to Kurdish exiles whom Turkey considers terrorists. The Scandinavians take a different view. They share the official position of the US and EU that the Kurdistan Workers’ Party (the PKK) is a terrorist organisation, but they note that i) not all Kurds oppressed by Turkey’s increasingly autocratic regime are PKK members; ii) the Kurdish YPG played a central role in defeating Isis in Syria; and iii) their domestic Kurdish communities pose no threat to Ankara.
Erdogan wants a change in tone on the Kurdish question from Finland (which hosts around 30,000 Turks and Kurds) and especially Sweden (which hosts around 230,000) but is unlikely to insist on the return of named exiles. He is more worried about…
Weapons. Turkey wants to use this crisis to get back into Nato’s Top Gun team. It wants F-35 fighters from the US but was dropped from the F-35 programme (even though it was a launch customer) for buying Russian S400 surface-to-air missiles in 2019. The Pentagon feared the Russian technicians who came with the rocket system would get a close-up look at America’s most advanced jet. Turkey was also barred from buying the F-16, and wants that ban lifted too.
Russia. This is the tightrope. Russians love sunbathing in Turkey and Erdogan has a close personal relationship with Putin. His S400 purchase was above all an assertion that an independent Turkish foreign policy means freedom to buy anything from anyone, and Turkey’s recent role hosting Russian-Ukrainian ceasefire talks showed it’s still trusted by both sides.

But…
Three senior Turkish officials who spoke to Bloomberg at the weekend said Ankara would agree to Nato expansion if its concerns about Kurdish militancy were taken on board and its military procurement goals were met.
They will be – most of them, at least. The war has created a new set of imperatives for Nato, and one is to find a way for Sweden and Finland to join. So in the end it will not only expand the alliance in the north but bind in Turkey more tightly in the south.

To note:
No wonder Biden says their Nato applications have America’s “full, total and complete backing”. Erdogan is not standing in their way. He’s just naming his price.
