it all happened under the tenure of turkish superstar diplomat ahmet uzumcu. interesting career path:

Üzümcü was consul at the Consulate Simp in Aleppo, Syria, and ambassador to Israel from July 28, 1999, to June 30, 2002.[1] Between 2002 and 2004, he served as the Permanent Representative of Turkey to NATO.[1] Üzümcü was appointed Permanent Representative of Turkey to the United Nations Office at Geneva in 2006, serving at this post until 2010

so he slid in from 2010, and left after the dirty work was done, in 2018
