What he said was that the Jewish lobby "more or less monopolise American foreign policy". I rather doubt they would agree with this claim. It was a dumb thing to say because the discussion will be about whether they do or not, rather than about anything to do with atheism.
No, that's not quite what he said.
That is to say, he said that with a qualifier:
yet they] more or less monopolise American foreign policy as far as many people can see.
(emphasis mine)
This is something completely ignored by the author of the follow-up linked in the OP as well. The statement quoted was not a statement about the actual influence exerted by the Jewish lobby regarding American foreign policy, rather it was a statement about the
public perception of that influence, something which the article author acknowledges during his criticism of Dawkins' statement:
This either means he believes that Jews monopolise policy on all foreign matters (say action on North Korea) or, more charitably, that he makes the common error of considering foreign policy towards Israel so important that no other foreign policy is worth mentioning.
(emphasis mine)
Clearly the author agrees that the pro-Israel Jewish lobby is commonly misattributed total power over American foreign policy, but he mistakes Dawkins for stating it as fact rather than as popular opinion.
Additionally, because I'm in the mood for nitpicking:
As a scientist, Dawkins surely can't approve the following statement - Jews support Israel, American foreign policy supports Israel, therefore the Jewish lobby controls American foreign policy. Yet this seems all he's left with.
While I agree that "Jews support Israel" is not uniformly true, it is firstly statistically accurate (most Jews do support Israel, I think) and
not even close to what Dawkins was implying. What prof. Dawkins was implying was the the
Jewish lobby supports Israel, which I think is something generally accepted to be true.
The author of this article conflates "Jews" and "the Jewish lobby" in order to accuse Richard Dawkins of that very mistake!
I make no claims to know prof. Dawkins' personal beliefs on this subject, I am merely reporting by reading of what he was reported to have said in this case, using only the referenced articles as source material. It may very well be the case that he intended the comment to be understood in the way that many people are reading it, but I doubt that to be the case.
