“Iran is not far from having a nuclear problem. They don’t have it, we know it,” Grossi said. “But the material for it already, it’s already there. To make a few warheads.”
The IAEA does not have "complete confidence that they have disappeared completely," he continued, adding that Iran had previously "conducted research and even tested some of the necessary elements for (a) nuclear device."
Grossi emphasized the technical difference between possession and capability, but he cautioned that the window is closing: "It would be a matter of months, not years."
