Now, many largely are silent a day after the landmark nuclear accord with world powers countries led by their foremost foil, the United States.
They offered little more than mild criticism as Iranians took to the streets to celebrate the historic accord. That may be because they don't want to go against the prevailing mood and they certainly don't want to be seen as being on the same side of the argument as Israeli Prime Minister Benjamin Netanyahu, who has called the deal a mistake of "historic proportions."
But that is far from certain. Iranians are hungry for relief from withering economic sanctions, and it is unclear if the timeframe Rouhani's team has agreed to will live up to expectations.
Iran's Supreme Leader Ayatollah Ali Khamenei, who holds the final word on all state matters, publicly backs Foreign Minister Mohammad Javad Zarif and his team. That in itself helps temper hard-line opposition.
