History may repeat itself. We don't forget the iconic scene of Iranian Minister Javad Zarif standing on the balcony of the Palais Coburg Hotel in Vienna eleven years ago, waving to journalists with a big joyful smile after signing the comprehensive agreement. It was a spectacular Iranian victory, signed by President Obama. All of Europe supported it, and China and Russia were witnesses. Vienna's joy was short-lived as the agreement was quickly torn up at the White House.
