The longstanding neutrality of Sweden and Finland was abandoned when both states submitted formal applications to Nato. But they are facing an unexpected obstacle on the way to membership: Turkey. While Turkey supports the alliance’s “open door” policy, Ankara’s veto reflects its aims to change the status quo and make gains in three areas: the eastern Mediterranean, Syria – and in its own domestic politics.
Turkey has always had bumpy relations with Nato. In 2009, Ankara blocked the appointment of the former Danish prime minister, Anders Fogh Rasmussen, as Nato secretary-general, because of his defence of free speech during the Danish cartoons crisis in 2006. He also allowed a rebel Kurdish TV station to broadcast from Denmark into Turkey. Another low point was in 2019, when Turkey started a military campaign against the Kurdish forces in Syria. This led to Nato secretary general, Jens Stoltenberg, criticising Ankara for “jeopardising” the fight against Islamic State.
The current crisis is in some ways a hangover from previous episodes particularly in relation to the Kurdish region in Syria. But it is unfolding against the backdrop of different geopolitical realities, including the deterioration of relations between the west and Russia, as well as a new domestic political context in Turkey.
