Who does the ceasefire benefit more - Iran or the United States?

After the extension of the ceasefire we ask critical questions about the new situation in the Middle East. Is this an open ended and indefinite extension of the ceasefire? Who does it benefit more? Does Iran’s refusal to come to Islamabad indicate its feeling stronger? Or is the regime internally divided, as Trump has claimed? Now, whenever talks happen, how can the key differences be bridged? And is either side willing to make the compromises necessary? Those are the key issues Karan Thapar raises with the Co-founder and Executive Vice President of the Quincy Institute for Responsible Statecraft, Trita Parsi.
