In an exclusive interview with Al Jazeera America, Dr. Hooshang Amirahmadi, President of the American Iranian Council, expresses his cautious optimism regarding the nuclear negotiations. He points out that two crucial issues remain, which include the extent of sanctions relief and the degree of nuclear research and development that Iran can undertake.

When asked if sanctions removal is Iran's biggest incentive to negotiate, Dr. Amirahmadi said, "Particularly sanctions on banking because that's really the killer. You could remove all sanctions on Iran except for banking and it wouldn't make a difference."
