On 17 May, Foreign Minister Ann Linde signed Sweden's NATO application and the next day it was handed over to NATO Secretary General Jens Stoltenberg.
Then there were many who thought that the process would go quickly.
But that put a stop to Turkey.
Magnus Christiansson, senior lecturer in military science at the Swedish National Defense College, is one of those who was surprised by Turkey's actions.
- Turkey has always existed as a factor because they have obstructed in previous processes.
But this time the situation looks a little different.
Turkey has been active and contributed to the war in Ukraine and since Sweden and Finland will join as a consequence of the war, I was a little surprised, he says.
Continued support for the Swedish NATO application
Among Swedes, 60 percent still believe that it is good that Sweden submitted an application to NATO.
A large majority, 83 percent, also believe that Sweden will become a member.
But it is a statistically significant decline compared to two weeks ago, when 89 percent thought that Sweden would be admitted.
It shows a new Novus survey.
- I think that Sweden will become a member of NATO, but I think it depends very much on how far Turkey is prepared to go to get American fighter jets and domestic political points, says Magnus Christiansson.
According to Christiansson, it is still possible that the knots will be untied for the NATO meeting in Madrid at the end of June.
- If it does not, I think the next stop is after the summer and the Swedish election, he says.
