VIENNA (Reuters) - Six world powers and Iran launch the decisive phase of diplomacy over Tehran's nuclear work during three-day talks starting in Vienna on Wednesday, with the aim of resolving their decade-old dispute by July 20 despite scepticism a deal is possible.
After three months of broad discussions about expectations rather than possible compromises, the sides now plan to start drafting the text of a final accord that could put an end to years of hostility and mistrust and curtail the risk of a new war in the Middle East.
