The reason why Turkey has been low on the NATO issue is that they have been waiting for the Swedish election, Turkish Foreign Minister Mevlut Cavusoglu explained in an interview with the state television channel TRT Haber this week. 

"However, we did not expect them to act before the election.

The government that will be formed after the election must take the necessary measures.

They know that the agreement will not be ratified by parliament if they neglect it," he said.

It is simply set up for quarrels with Sweden's next government.

The talks may be less infected as the previous government's dealings with Syrian-Kurdish politicians and Amineh Kakabaveh's wave master role were a major source of irritation in Ankara. 

But Turkey's hard-to-digest, if not impossible, demands remain even for a new Swedish government to deal with.

Among other things, Turkey demands the extradition of people identified as terrorists in order to allow Sweden and Finland to become full members of the defense alliance.

Turkey's evidence has been described as very thin.

During the NATO summit in Madrid in June, an agreement was concluded with Turkey as a condition for Sweden and Finland to receive the status of applicant countries.

But the ink didn't have time to dry before opinions differed on what was actually agreed upon.

Turkey believes it has been promised extraditions, while Sweden believes it is up to the Swedish legal system.  

Turkey is now expected to use the ratification in parliament as a new opportunity to put pressure on Sweden.

So far, 26 NATO countries have approved Sweden and Finland as NATO members in their parliaments.

Slovakia, Hungary and Turkey remain for membership to be completed.

But there may also be another explanation for why Turkey is in a hurry to revive the NATO issue.

There are many indications that Turkey's blocking of Swedish and Finnish NATO membership is also being used as a means of pressure to buy the American fighter jet F-16. 

Next week, President Recep Tayyip Erdogan travels to New York to participate in meetings of the UN General Assembly.

According to Reuters, a meeting between Erdogan and US President Joe Biden is then planned. 

In order for Turkey to be able to buy the fighter jet, a majority is required in the US Congress, where there is strong opposition to arms exports to Turkey.

Joe Biden promised Turkey to give its support in the matter at the same time as Sweden and Finland were released as applicant countries. 

Thus, the Nordic NATO enlargement became a bat for Turkish fighter aircraft purchases.

It is likely that the NATO issue will also be a headache for Sweden's next foreign minister.
