Will the US join Israel in its offensive against Iran? President Donald Trump says, "I may do it, I may not do it." Residents of Tehran have been called upon to evacuate and are mired in traffic gridlocks trying to leave. Meantime, Israel continues to strike leadership targets and nuclear sites. Iran's Supreme Leader, Ayatollah Khamenei, rejected the U.S. President's call for unconditional surrender in a taped video message aired on State TV. Majid Takht-Ravanchi is Iran's Deputy Foreign Minister, and is a key player in the nuclear negotiations. He joins Christiane in an exclusive interview from Tehran.
