A sayanim (sing. Sayan; Hebrew: helpers, assistants) is a Jew living outside Israel who volunteers (or more appropriately is emotionally blackmailed) to provide assistance to Israel and/or the Israeli Mossad utilizing the capacity of their own nationality to procure assistance. This assistance includes facilitating medical care, money, logistics, and even overt intelligence gathering. Estimates put the number of sayanim in the hundreds of thousands.
“With a network of ‘sayanim’ scattered everywhere throughout the world (as described by ex-Mossad officer Victor Ostrovsky in his book ‘By Way Of Deception’) Israel literally has millions of eyes and ears, watching and listening to everything as it all pertains to the Jewish state.”
