While many on the American side were excited about the possibilities opened by President Obama's historic phone call with Iranian President Hassan Rouhani, many Iranians were decidedly less so. When Rouhani returned to Tehran after the diplomatic conversation after the U.N. General Assembly in New York, his car was beset by crowds—not all of them friendly. About 100 protestors met him at the airport, shouting, "Death to America." One protestor threw a shoe at the presidential car, which in Islamic countries is considered a much graver insult than you'd think. It's not the only complication Rouhani ran into after the phone call: several tweets were taken down on Friday after details of the conversation appeared to be divulged from an account in Rouhani's name.
