The failure of Iran and the P5+1 (the five permanent members of the UN Security Council plus Germany, also known as EU3+3) to reach a comprehensive nuclear agreement by their self-imposed 24 November deadline was no surprise. The process had been deadlocked for months over two key issues: the size of Iran’s enrichment program and sanctions relief. For want of a last-minute breakthrough, the parties agreed to a new seven-month extension, with the goal of reaching a political agreement by 1 March 2015 and a comprehensive agreement, including an implementation plan, by 1 July 2015. A landmark agreement can still be found if both sides adopt more flexible postures. As Crisis Group has previously written and here reiterates, they can do so without violating their core principles and interests.
