“I don’t believe in trusting politicians,” the former New York mayor Koch said in a radio show with Aaron Klein, a Jerusalem-based right-wing author whose two new titles accuse Obama of being a secret Socialist. Still, Koch is campaigning for the president out of pragmatism: “I believe that he is going to win whether I vote for him or not. I believe that he is going to win. So wouldn’t it be better that he wins changing his positions?” he explained. The position Koch most wants to change? Obama’s wait-and-see strategy with Israel and Iran. “We should say that an attack upon Israel is an attack upon the United States and that we will militarily respond,” he said.
