Out of the three reporters from the Jersualem Post I could find willing to use the phrase "Arab lobby" only Alan Dershowitz is cocky enough to wag his finger at someone for doing something he did only 2 years ago.
Somehow this guy is still around. He wrote this about Arab foreign influence (evidently he had in mind only the Saudi lobby) in the US:
The methodology employed by the Arab lobby is thus totally inconsistent with democratic governance, because it does not reflect the will of the people but rather the corruption of the elite, while the Israeli lobby seems to operate within the parameters of democratic processes.
Then in 2012:
Hagel’s appointment would send another disturbing message to the bigots of Tehran, who believe that the only people calling for military action against Iran are “the Jews.” Hagel speaks their language. He is the only mainstream American politician to talk openly about how “the Jewish lobby intimidates a lot of people.” Others refer to the “Israel lobby,” which includes Jews, Christians, and others. They understand that not all supporters of Israel are Jewish, and that not all Jews are part of the Israel lobby. But Hagel apparently sees things in terms of Jewish interests versus American interests.
