Jason Zengerle writes about Peter Beinart in an article titled The Israeli Desert.
In talking to various Jewish journalists about Beinart over the past few months, I heard the words shmegegge and “Sammy Glick,” as well as this joke: “A yeshiva student goes to his rabbi and says, ‘Rabbi, I had a dream last night that I was the leader of a Hasidic court and I had 300 followers.’ The rabbi says, ‘When 300 Hasidim have a dream that you’re their leader, come back and we’ll talk.’
...Beinart and Goldberg’s biggest disagreement on Israel may have to do with how they acquired their understanding of the Israeli-Palestinian conflict. Although Beinart has been to the West Bank on several occasions, he readily concedes that he derives much of his knowledge of the situation there from what he reads....Goldberg, by contrast, has reached most of his conclusions from firsthand observation during his fifteen years reporting from the West Bank and Gaza, and he bridles when, for instance, Beinart argues that Hamas has made certain statements that suggest a greater (albeit insufficient) openness toward accepting a two-state solution. “I’ve spent a lot of time with Hamas over the years, and I feel like I have a better sense of Hamas than Peter does,” he says. “I hereby invite Peter to Gaza with me, and we’ll spend a couple of weeks in the mosques, and then he’ll tell me if he thinks that they’re philo-Semitic or non-anti-Semitic or non-annihilationist in their fundamental outlook.”
