On September 4, President Hassan Rouhani used Twitter to wish a happy new year to the world’s Jews. Iran is home to some 25,000 Jews—the second largest population in the Middle East outside of Israel. His tweet contrasted starkly with the tone of his predecessor Mahmoud Ahmadinejad, who repeatedly challenged Israel’s right to exist between 2005 and 2013. “We say that this fake regime [Israel] cannot logically continue to live,” he said at the 2005 World Without Zionism conference in Tehran. “Open the doors (of Europe) and let the Jews go back to their own countries.”
