U.S. Secretary of State John Kerry joins MSNBC’s Morning Joe and talks with Mike Barnicle about the erroneous statements being used by opponents of the U.S.-Iran nuclear agreement. “How quickly, in your estimation, would the Iranians get to a nuclear weapon without an agreement—and how quickly would money flow into Iran without an agreement?,” asks Mike. Listen to Secretary Kerry’s response and why he believes a potential failed agreement would only prove the Middle East’s worst fears about the West and push the Iranians toward a nuclear weapon.
