Even if you want to talk about Israels ‘security’ in the narrowest terms what Friedman says is – to borrow a phrase from the article – utter bullshit. Consider the wall, which Friedman mentions in his article – Israeli economist Shir Hever quotes General Yair Golan:
And, in fact, the wall, even though Israel calls it the security barrier officially, in a meeting in which I was present, the brigadier general Yair Golan, the former commander of the Israeli forces in the West Bank, told the people present that in fact the wall [was] not built in order to provide security. It was–his orders that he received from the Israeli government were that the wall’s first purpose is to separate between people, meaning that the wall’s true intention is to prevent Israelis and Palestinians from meeting each other, becoming friends, getting married, and its secondary purpose is to provide security. And that’s one of the reasons also why the wall is moving all the time, because they’re trying to incorporate as many Jews as they can on the Israeli side of the wall, but at the same time trying to exclude [as many] Palestinians as they can on the other side, on the east side of the wall. This is the reality.
Elsewhere Golan has said that the suicide bombings are prevented by intelligence, not the wall. So much of the Hasbara discourse is directly contradicted by people in Israels own security establishment. It’s weird.
