With Iran’s attack on Israel, is World War III a real possibility?

Today, On Deadline is turning our gaze to the Middle East where the situation worsened over the weekend when Iran launched an attack on Israel. This attack brings a fourth nuclear power into a world stage of battles. Russia continues its invasion of Ukraine, Israel is fighting Hamas in Gaza, and the U.S. has been providing help to both Ukraine and Israel. How close does all this conflict bring us to nuclear escalation? 'On Deadline' is hosted and produced by Lauren Barry. It's also produced by Joe Hiti, Christy Strawser and Myron Kaplan.
