US-Iran deal not likely to affect Syrian revolution "The military-supported political system has crumbled. It is thriving on Iranian support. It cannot hold out for long. Syrians no longer consider Assad senior or his son as their national leaders. Most of them have now realized that Assad is the leader of a tiny sect. It is impossible to believe that a regime rejected by Sunnis, constituting more than 70 percent of the country’s population, could survive. In the current scenario, it is unlikely that the Assad’s regime will survive. It now maintains authority only in a few pockets. When we say that the regime’s survival is impossible, it does not mean there is a suitable national alternative available."
