Israel's president and prime minister are trading charges over making peace with the Palestinians. President Shimon Peres told a summit of international ambassadors and diplomats Sunday that Palestinian President Mahmoud Abbas is a reliable peace partner. He said Israeli diplomacy must change "from an aggressive approach to a moderate approach of dialogue." Prime Minister Benjamin Netanyahu's party and his hawkish election partner released a statement calling the Israeli president out of touch and labeling the Palestinian president a "peace rejecter."
