I read that he was involved in the American Jewish Committee.
Well well…in the mid 1980s in Berkeley, me a Diaspora Palestinian, I was invited along with a Palestinian Israeli (1948) psychology student to speak about possibilities of peace by the Bay area chapter of the AJC on the prodding by the liberal zionist director of the American Friends Service Committee at that time (Quakers). So we spoke, it was supposedly a moving experience, many questions, some old ladies cried and hugged me etc.
There was a guy, named John Rothman who seemed to be a wheeler and dealer there, came to me, appeared curious, and empathetic, and acted nice in front of the old ladies. He asked a few social questions etc. Low and behold, a few days letter an article in the “Jewish Bulletin (if I recall the name correctly) comes out penned by this John Rothman, attacking the local AJC leadership for providing a forum for dangerous PLO terrorist sympathizers etc etc. ( in those days the PLO was the big No No. )Within a month or two the director of the local chapter of the AJC, a man I only remember his first name as “Joel” was sacked from his position. I remember him as a kind and bearded man, who wanted to provide a forum and a question and answer with the other side. it was a great lesson to me.
John Rothman became famous and moved up the Zio-ladder, as an extreme Zionist ideologue, wrote books and became a talk-show host in the San Francisco bay. He is one of the worst of the worst right-wing Zionist ideologues out there, while pretending to have a liberal point of view in other arenas, as a good Bay Area guy.
