Lashing out at his country’s critics, Israeli Prime Minister Benjamin Netanyahu angrily dismissed allegations of Israeli genocide in Gaza as “the biggest lie of the century” in a defiant speech to the U.N. General Assembly that asserted his nation’s right to wage war against Iran. Scores of delegates trooped out of the hall in protest. Netanyahu addressed the plenum after days of speeches by world leaders condemning Israel’s war in Gaza and accusing him of orchestrating a genocide against the Palestinian people. At times, the Israeli leader, facing a tough race for re-election next month, became emotional and indignant as he lectured his critics, among them New York’s mayor.
