In an exclusive interview with Al Jazeera America, Dr. Hooshang Amirahmadi, President of the American Iranian Council, asserts that while there has been some cooperation on various fronts between the U.S. and Iran, a nuclear deal is vital for maintaining any progress that has already been made.

When asked whether President Rouhani or Obama has a harder time selling the deal, Dr. Amirahmadi said, "I think President Obama. Because in Iran you have a central figure named Ayatollah Khamenei and everyone will listen to him in the final analysis."
