The Sabbatean-controlled Derin Devlet deep state domestic intelligence apparatus is highly secretive and most likely does not maintain many diplomatic relationships with the outside world, if any indeed. The question still lingers however, does the Derin Devlet maintain a diplomatic relationship with Israel through Tevel, the Political Action and Liaison Department of the Mossad? This is a serious question considering the importance of regional coordination between Derin Devlet and Tevel. There should furthermore be much room for intelligence cooperation if this indeed does not already exist of course. In case the Derin Devlet does not already have a diplomatic relationship with Tevel, they would be particularly well-advised to establish one.
