The founders of Standing Together built one of the most impressive Jewish-Arab spaces created here in the past generation. It would be a pity to trade so rare a political asset for a small partyI was about 10 years old when I asked Haim Hanegbi what the Matzpen organization actually was. "This," he said, pointing to the five members sitting in the small living room in Ramat Aviv, "this is Matzpen." In that reply, half mockery and half pride, lies the essence of something deeper than a joke about the size of a left-wing political movement.
