Sayanim (single. Sayan; Hebrew: helpers, assistants) are Jews living outside Israel who volunteer to provide assistance to Israel and/or the Israeli Mossad utilising the capacity of their own citizenship to procure assistance. This assistance includes facilitating medical care, money, logistics, and even overt intelligence gathering. They can be Judges, Court Clerks, Expert Witnesses, Child Protective Service Workers, Assistant District Attorneys, Police Officers, or anyone with a great degree of power over people’s lives, and will do anything at the behest of Mossad case officers (katsa) for the Jewish terrorist organisation called Israel. Estimates put the number of sayanim in the hundreds of thousands. While not official Mossad agents and sometimes acting without explicit knowledge, they may work in the capacity of unregistered representatives of the government of Israel in their respective nations. Generally-speaking, these non-Israeli Jewish volunteers are asked to engage in low level activities that will not bring them into trouble with the authorities, such as using Wikipedia to spread propaganda. There are exceptions like the case of Jonathan Pollard, the U.S. Naval intelligence employee who engaged in espionage on behalf of Israel’s intelligence agencies and whose exposure by the FBI strained relations between the U.S. and Israel.
“The next day Ran S. delivered a lecture on the sayanim, a unique and important part of the Mossad’s operation. Sayanim—assistants — must be 100 percent Jewish. They live abroad, and though they are not Israeli citizens, many are reached through their relatives in Israel. An Israeli with a relative in England, for example, might be asked to write a letter saying the person bearing the letter represents an organization whose main goal is to help save Jewish people in the Diaspora. Could the British relative help in any way?
There are thousands of sayanim around the world. In London alone, there are about 2,000 who are active, and another 5,000 on the list. They fulfill many different roles. A car sayan, for example, running a rental agency, could help the Mossad rent a car without having to complete the usual documentation. An apartment sayan would find accommodation without raising suspicions, a bank sayan could get you money if you needed it in the middle of the night, a doctor sayan would treat a bullet wound without reporting it to the police, and so on.
The idea is to have a pool of people available when needed who can provide services but will keep quiet about them out of loyalty to the cause. They are paid only costs. Often the loyalty of sayanim is abused by katsas who take advantage of the available help for their own personal use. There is no way for the sayan to check this.
One thing you know for sure is that even if a Jewish person knows it is the Mossad, he might not agree to work with you — but he won’t turn you in. You have at your disposal a non risk recruitment system that actually gives you a pool of millions of Jewish people to tap from outside your own borders.It’s much easier to operate with what is available on the spot, and sayanim offer incredible practical support everywhere. But they are never put at risk — nor are they privy to classified information.” – Former Mossad Officer Viktor Ostrovsky “By Way Of Deception: The Unmasking Of A Mossad Officer” p.86-87
