Though Turkey has officially supported Nato enlargement since it joined the US-led alliance 70 years ago, its opposition could pose a problem for Sweden and Finland given new members need unanimous agreement.
Turkey has repeatedly slammed Sweden and other Western European countries for its handling of organisations deemed terrorist by Ankara, including the Kurdish militant groups PKK and YPG, and the followers of US-based Islamic cleric Fethullah Gulen. Ankara says Gulenists carried out a coup attempt in 2016. Gulen and his supporters deny the accusation.
Finland’s plan to apply for Nato membership, announced Thursday, and the expectation that Sweden will follow, would bring about the expansion of the Western military alliance that Russian President Vladimir Putin aimed to prevent by launching the invasion of Ukraine.
“We are following the developments regarding Sweden and Finland, but we don’t hold positive views,” Erdogan told reporters in Istanbul, adding it had been a mistake for Nato to accept Greece as a member in the past.
“As Turkey, we don’t want to repeat similar mistakes. Furthermore, Scandinavian countries are guesthouses for terrorist organisations,” Erdogan said, without giving details. “They are even members of the parliament in some countries. It is not possible for us to be in favour,” he added.
In response, Finnish Foreign Minister Pekka Haavisto urged patience and called for a step-by-step approach in response to Turkish resistance. He also said he was due to meet his Turkish counterpart in Berlin on Saturday.
Meanwhile, Sweden said it remained confident it could secure unanimous backing for any Nato application it could submit.
Nato Secretary-General Jens Stoltenberg had said the Finns would be “warmly welcomed” and promised a “smooth and swift” accession process, which is also backed by Washington.
Aaron Stein, research director at the Foreign Policy Research Institute, said on Twitter with respect to Turkish opposition: “Turkish national security elites view Finland and Sweden as semi-hostile, given the presence of PKK and Gulenists. It’s gonna take arm twisting to get sign-off.” Nato states that membership is open to any “European state in a position to further the principles of this Treaty and to contribute to the security of the North Atlantic area”.
Finland and Sweden are already Nato’s closest partners, sitting in on many meetings, getting regularly briefed on the situation in Ukraine and taking part in regular military drills with Nato allies. Much of their military equipment is inter-operable with Nato allies.
