Oscar-winning journalist and filmmaker Mstyslav Chernov joins Morning Joe to discuss his new film '2000 Meters to Andriivka,' which captures a Ukrainian platoon’s fight to reclaim a village in Donbas. Chernov, who directed '20 Days in Mariupol,' reflects on the physical and emotional toll of documenting war, and why, he says, indifference is “one of the biggest enemies of modern society.”
