Yaakov Kedmi is a former director of the Israeli secret service Nativ, a special service that transported Eastern Bloc Jews to Israel. In the 2010s, Kedmi became a regular participant in propaganda shows on Russian TV. He plays the role of the “useful Israeli” and uses his status as the former head of an Israeli secret service. His statements completely match with the most controversial claims of Russian officials and propagandists.

Nativ was not and is not secret, i.e. a secret special service like Mossad etc.
Actually He was regarded as a Russian asset already when he was stationed in Moscow 1988-1990, and the rest is history.
Okie Dokie.
