For one thing, the majority of the testimonies seemed to reflect the roughness of the military rather than any human rights abuse. The indignity of checkpoints; the intrusion of house-to-house searches; the unpleasantness of curfews. All of this stuff is awful, but only a small percentage of it appeared to warrant court martial.

I couldn’t shake the feeling that Breaking the Silence was milking it.

It was only a hunch at first. But later, the bias of the organisation became clearer. During a break between interviews, I asked Yehuda Shaul, one of the founders of the organisation, how the group is funded. It was with some surprise that I learned that 45 per cent of it is donated by European countries, including Norway and Spain, and the European Union. Other donors include UNICEF, Christian Aid and Oxfam GB. To me this seemed potentially problematic….It appeared that these former soldiers, some of whom draw salaries from Breaking the Silence, were motivated by financial and political concerns to further a pro-Palestinian agenda. They weren’t merely telling the truth about their experiences. They were under pressure to perform.

Indeed, I later discovered that there have been many allegations in the past that members of the organisation either fabricated or exaggerated their testimonies.

The matter became more unsettling when one of Breaking the Silence’s former soldiers accompanied me to Hebron…

We set up our video camera outside an army base in the Israeli sector of Hebron, and I began to interview the former soldier from Breaking the Silence. He was talking about his army service, and came out with the line, “the first time I ever met a Palestinian was when I entered his house in the middle of the night”.

While he was speaking a car drove by behind him, drowning out his words. I said: “Just give me it one more time about how… the first time you ever met a Palestinian was when you kicked down his door in the middle of the night”. This was my mistake; he hadn’t said that he kicked down anything.

He duly repeated it. This time, however, he took my lead and changed his account from “entered his house in the middle of the night” to “kicked down his door in the middle of the night”. On the surface it may seem like a small detail. But when we played back the tape I found the ease with which he exaggerated his story very troubling. We didn’t use the interview.

Most worryingly of all, Breaking the Silence focuses almost exclusively on Hebron, presenting it as typical. Several times a month it ships foreign diplomats, officials and ordinary folk to this unhappy place, showing them the grim military infrastructure and providing testimony about the abuses carried out by settlers and soldiers.

The group does not offer tours to any other settlements on the West Bank. This one city, they say, is a “microcosm of occupation”.
