No, this isn’t self-defeating at all:
Is Rabbi Lerner aware that he’s taken an issue around which there might be some mainstream consensus — opposition to U.S. military action against Iran — and turned it into an attack on a major Jewish group?
Not that AIPAC is so easily bruised, but the debate should be about whether or not the real or possible threat of an Iranian nuke justifies a military response. Lerner changes the subject, and provides yet another arrow in the quiver of those who insist American foreign policy is in thrall to the Jews.
Despicable. And dumb.
