I went to see a film at DocAviv, the Tel Aviv documentary film festival, at the weekend about a Palestinian man who acts as an informant for the Israelis, and the dark consequences for him and his family.
The Collaborator and His Family is the compelling and dispiriting story of Ibrahim from the West Bank town of Hebron, who passes information to his Israeli handlers - not for money, nor because he is being blackmailed, but because he thinks violent attacks on Israelis are wrong. "I was on Israel's side," he says.
Collaborators are likely to be killed if discovered, and their families ostracised. Ibrahim, fearing he is about to be exposed, flees to Tel Aviv and later brings his wife and five children to join him.
They live in a bleak, desperate part of the city in a crumbling, leaking apartment. But, worse, they have no official status despite repeated yet unfulfilled promises by Ibrahim's "operator" to arrange a "permit" to live in Israel.
Without this documentation, the family is in constant fear of being deported back to the West Bank. Tensions mount, particularly between Ibrahim and his three sons, who are simultaneously running into trouble with the law and being targeted as potential informants themselves.
It is a gloomy portrait of a dislocated family struggling to survive on the margins of a society which doesn't want them and unable to return to their home. "I admit I am a traitor. I sold my people. But for what?" says Ibrahim.
His story is not unique, and not even unusual. A report last year by the Legal Forum for the Land of Israel estimated that 6,000 Palestinian collaborators and their families have moved to Israel but not been given adequate protection or proper status, and have essentially been abandoned by the security establishment to which they passed information.
In an interview with the Jerusalem Post, the author of the report, Israeli lawyer Michael Teplow, said: "There are literally thousands of threatened people who have been living in Israel for more than ten years with a special [temporary] permit but who are not allowed to work and do not receive health benefits. These people go through serious mental anguish every three months when their permit has to be renewed. They never know if they might be suddenly arrested [by the Israeli authorities] and returned across the border."
Collaborators and informants are shown little mercy by Palestinian security forces. There have been many documented cases of collaborators being killed by mobs or subject to summary executions. Their families are forced to disown them, and even so are usually shunned by the community.
Earlier this month, a Palestinian convicted of collaborating was executed by firing squad in Gaza. Under Palestinian law, collaboration is punishable by death.
Israeli military intelligence relies heavily on informants, who are often recruited by blackmail or financial inducements.
Ibrahim, the central character in The Collaborator and His Family, finds it difficult to live with the choices he made. And his wife and children, who didn't make those choices, find it even harder.
