Crisis Group is one of the best resources one has to understand international policy better. I have frequently read their reports, and I fully agree with their stances. Ali Vaez frequently appears on Persian TV and I consider him the best commentator on Iran’s international policy. Anyway they have a 40 page report on how the nuclear talks could be successful, and it’s a must read for everyone interested in the subject. The report itself is not new but it’s been edited and it should be read.
