Israeli Prime Minister Benjamin Netanyahu is continuing a public campaign to cast doubt on diplomatic engagement with Iran. Speaking before the U.N. General Assembly, Netanyahu accused new Iranian Prime Minister Hassan Rouhani of deceiving the world about Iran’s nuclear program. He also renewed a threat to launch military strikes.

Israeli Prime Minister Benjamin Netanyahu: “Now, I know, Rouhani doesn’t sound like Ahmadinejad. But when it comes to Iran’s nuclear weapons program, the only difference between them is this: Ahmadinejad was a wolf in wolf’s clothing; Rouhani is a wolf in sheep’s clothing, a wolf who thinks he can pull the eyes—the wool over the eyes of the international community. Israel will not allow Iran to get nuclear weapons. If Israel is forced to stand alone, Israel will stand alone. Yet in standing alone, Israel will know that we will be defending many, many others.”

Netanyahu’s comments come days after a phone call between President Obama and Rouhani, the highest-level U.S.-Iran contact in decades.
