J Street head Jeremy Ben-Ami debated the Executive Director of the American Jewish Committee David Harris on CNN earlier this week. They disagreed on some key points (Harris believes Israel can solve the conflict on its own while Ben-Ami believes only Washington can) but this comment by Ben-Ami was the strongest statement:
The settlement enterprise is essentially the equivalent of a cancer eating away at the state of Israel. It’s a disease that needed to be stopped early, and unfortunately, it’s now taking over the chances of Israel’s survival as a Jewish democratic state. And so I think it has been a mistake on the part of lobbyists in America who have tried to help Israel and facilitate the continued settlement expansion.
