There are thousands of sayanim around the world

 The sayan is a person who would betray the nation of which he is a citizen out of devotion to a notion of a clannish brotherhood.
While in its early days, Zionism presents itself as an attempt to bring the world Jewry to Zion, in the last three decades it has become clear to the Zionist leadership that Israel would actually benefit from world Jewry, and especially the Jewish elite, staying exactly where they are. Paul Wolfowitz, Rahm Emmanuel, Lord Levy and David Aaronovitch have proved far more effective for the Zionist cause by staying where they are. Gilad Atzmon

‘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 telling the person bearing the letter that he 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.’
