A deal has officially ended the fighting, but the harder negotiations are just beginning.

Both sides have sold the deal to their public as a win but, as our analysts here explain, neither has fully convinced them and domestic critics on both sides argue that too many concessions were made.

For Iran, the deal with the US offers something just as important as a ceasefire: a way to claim that it has not just survived the war without surrendering but has emerged from it stronger.

From the start, Tehran's core objective was not necessarily to defeat the US and Israel in conventional military terms. It was to come out of the conflict with the Islamic Republic intact, its leadership still functioning and its negotiating position not completely broken.
