Iran and the International Atomic Energy Agency (IAEA) have signed an agreement to resume cooperation, allowing IAEA inspectors to return to the Islamic Republic. The move has been welcomed by international observers as a breakthrough, bringing a long-stalled nuclear issue closer to a resolution and offering a glimpse of “light at the end of the tunnel.”

The window for negotiations on the Iran nuclear deal is closing as the parties take increasingly hard-line positions. Ten years since the signing of the historic agreement, Europe now finds itself at a crossroads: to continue pursuing diplomacy or to reimpose sanctions and increase pressure on Tehran.
