J street is doomed for failure against Aipac, I fear. Aipac has no limit to the unsavory and undemocratic censorship and smearing it uses against even it’s loyal opposition. Its defense of the indefensible atrocities that help Israel maintain its illegal occupation of its neighbor’s lands is not good for Israel! Israeli lives are Aipac’s collateral damage for billions of dollars of American aid.
