Writing in Al Jazeera, Bahçeşehir University’s Gülnur Aybet discusses the issues Vice President Joe Biden will need to tackle along with President Erdogan during the former’s trip to Ankara. Key among these is the extradition of Fethullah Gülen:

The relations of Turkey and the United States were not in a very good state before the failed coup attempt on July 15. However, since then relations have taken a turn for the worst. As Vice President Joe Biden visits Turkey today, he is facing four pressing items on the agenda.

The first is the Turkish request for the extradition of Fethullah Gulen, who is widely believed to be the hand behind the failed coup attempt.

Further evidence coming from the testimonies of the arrested coup plotters indicates without a doubt that FETO was behind the coup attempt.

However, from Turkey’s perspective, the US leadership appears to have a nonchalant attitude towards the extradition request.

Whether this is true or not, it is up to the US authorities to convince their Turkish counterparts that they are taking the matter seriously and are urging the legal process to move with the upmost speed. Much of this convincing will fall on Joe Biden during his visit.
