While the deal provides assurance for the international community that Iran would not have the hardware to make nuclear weapons and places its program under intrusive inspection, it also, Iranians hope, could change the course of their country. People are optimistic that with the lifting of international pressure, the economy will improve and they can find the space to force the regime to respect human dignity and rule of law.
With the deal, the country's Islamic rulers had finally broken the taboo of speaking to the United States, often referred to as The Great Satan. For 20 months, Iran's foreign minister, Javad Zarif, and Secretary of State John Kerry spent more time with one another than they did with any other foreign official.
Now, liberal forces in Iran who brokered the deal, need to work further with their American counterparts to see that it is implemented. Analysts believe the process will empower them and marginalize hardliners, whose hawkish policies at home and in the region, and support for Bashar al-Assad's regime in Syria, have been a source of embarrassment for many Iranians.
Political scientist Sadegh Zibakalam, a professor at Tehran University, told The Guardian that the nuclear deal will most likely translate into greater electoral support for the liberals in the 2016 Parliamentary elections. Because of their engagement with the West, they will be forced to craft policies that are more responsive to international demands.
