Michael Sahlin is a former ambassador to Ankara and State Secretary at the Ministry of Defense.

He describes the development of recent days as "dizzying and a little surprising" - both the steps there and the end product.

- When I look at this agreement, I see the product of very tough negotiations, where Turkey has pushed for and wanted as concrete things as possible and Sweden and Finland have parried through different types of braces and belts so as not to be cut too much in his freedom of action, says Sahlin in SVT's Morgonstudion and continues:

- The result will then be a text that opens up a lot of questions of interpretation.

Turkish election movement is underway

And yet it is not clear.

Although support for Swedish and Finnish membership is strong from the other 29 NATO countries, the accession protocol must be ratified in the parliaments of the various countries.

A process that in previous enlargements took nine to fourteen months.

- There is an uncertainty left because this will be ratified sometime this autumn in the Turkish parliament and that Turkish parliament may then be in an election campaign, Sahlin says.

"The last moment of concern"

Turkey's Minister of Justice has already demanded that 33 people, who are described as terror suspects, be extradited from Sweden and Finland.

- It will be a very interesting process in the coming months.

It will be sweaty to hold on to, so that there will be no disagreement again.

Jan Hallenberg, research leader at the Foreign Policy Institute, shares that view.

- The last remaining point of concern, if you want Sweden and Finland to join, is when Erdogan realizes that a lot of Kurds will not be extradited, what does he do then?

Does he tell his parliament that they should vote no?

I do not think so, but it is not totally out of the question, says Hallenberg to SVT Nyheter.

- I think that risk is small, but it is not zero.

On Thursday, President Recep Tayyip Erdogan also claims that Sweden has promised to extradite 73 "terrorists".

He added that ratification would not be sent to parliament if the promises made to Turkey were not kept.
