Iran's Nuclear Progamme
Darya Dolzikova of The Royal United Services Institute, a think tank, told Newsweek: "Iran has had plenty of opportunity to show that it's willing to engage in good faith. There are issues on the table with the IAEA that remain unresolved for Iran, or rather that Iran has not resolved. And there's plenty of opportunity for Iran to demonstrate that it's willing to engage in potential nuclear negotiations."
