Israelis fear PM is meddling in US politics - Yahoo! News JERUSALEM (AP) It is a taboo for Israeli leaders to give even the slightest hint of favoritism in politics in the United States, Israel's closest ally. So some Israelis are squirming over a perception that their prime minister is siding with Republican Mitt Romney in the U.S. presidential race, in the belief he will take a harder line on archenemy Iran if elected. With President Barack Obama holding a narrow lead in opinion polls, Benjamin Netanyahu's perceived strategy looks risky to Israelis who fear their alliance with the U.S. could be in trouble if the incumbent wins. "If our prime minister doesn't get along with their leader, it will hurt our relations," said Shai Hugi, 20, a car rental clerk in Jerusalem. "The United States is Israel's best ally, and it's always good that you have a strong friend behind you." Netanyahu, convinced that Iran is close to developing nuclear weapons, says Tehran must be stopped. Claiming international diplomatic efforts and economic sanctions have failed, Netanyahu says the threat of force must be seriously considered. He has urged Obama to declare "red lines" that would trigger an American attack on Iran's nuclear facilities, coupling his appeals with veiled threats of a unilateral Israeli attack on Iran.
