The head of Israel’s Mossad intelligence service said on Tuesday that the country must “ensure” Iran doesn’t restart its nuclear program, six months after it bombed Tehran’s atomic facilities during a 12-day war.“The idea of continuing to develop a nuclear bomb still beats in their hearts. We bear responsibility to ensure that the nuclear project, which has been gravely damaged, in close cooperation with the Americans, will never be activated,” David Barnea said at an award ceremony for Mossad agents in Jerusalem.
