From the earliest centuries of Torah teaching and debate, continuing down through the age of the Talmud and the great commentators Jews have practiced vigorous hair-splitting disagreement. This is not treason. AIPAC was in danger of becoming a victim of its own past success. Its blind loyalty to Israel and its lockstep mentality had led it into danger. It was becoming notorious in the US and many were calling for it to be registered as a foreign agency. With the rise of J-Street free speech and balance are returning to the diaspora. Hopefully, free speech and balance will return to Israel soon.
