'Dark hour in our shared history'

Those are the words of President Biden to the world, as the war in Ukraine enters its fourth month. Ukraine’s President Zelensky meanwhile told the annual gathering at Davos that he fears the world is losing interest, that momentum behind Ukraine is fading. He appealed “not to lose this feeling of unity.” Sergiy Kyslytsya is Ukraine’s Ambassador to the United Nations. He’s spent the last three months since the invasion driving home the horror of this war, unafraid to confront his Russian counterparts, and he joins Christiane from New York.  Also in today's show: Mohammad Shtayyeh, the Palestinian Authority Prime Minister; Nina Jankowicz, who just resigned from Homeland Security’s newly launched Disinformation Governance Board.
