US National security adviser Susan Rice met Israeli leaders Wednesday after the collapse of US-brokered Middle East peace talks and amid allegations Israel was spying on its principal ally. Rice started her visit by meeting Prime Minister Benjamin Netanyahu. "They discussed a wide range of regional and bilateral issues, including the United States and Israel's close security cooperation, which has been unprecedented under President Obama?s leadership," a White House statement said. "On Iran, Ambassador Rice... reiterated that the United States will **t allow Iran to acquire a nuclear ******, and that diplomacy is the best way to resolve the international community's concerns peacefully," it added.
