After a rare moment of unity on nuclear weapons bitter divisions have again come to the surface at the UN. Israeli Prime Minister Benjamin Netanyahu launched a scathing attack on Iran’s President Mahmoud Ahmadinejad for denying the holocaust.Brandishing wartime documents he told the General Assembly: “Here is a copy of minutes of the meeting of senior Nazi officials instructing the Nazi Government exactly how to carry out the extermination of the Jewish people. Is this protocol a lie?” He also condemned delegates who did not join others in walking out during Ahmadinejad’s speech to the General Assembly earlier. It came after the Security Council backed a US resolution on ridding the world of nuclear arms. Israel and western countries fear Tehran is trying to develop nuclear bombs but the resolution did not mention Iran, to Israel’s dismay.
