Fault Lines welcomes multiple NSI authors for conversations about their recent publications. First, Les talks with NSI Visiting Fellow Matthew Ferraro about his backgrounder entitled Decoding Deepfakes. After that, NSI has a conversation with NSI Visiting Fellow Vince Vitkowsky and Rachida Mecheri on their Law and Policy Paper entitled Responding to China at the United Nations. Should we be worried about more fake media? How is China pushing its agenda at the United Nations? How can the United States and its allies take on these twin challenges? Les explores these questions and more on this week’s Fault Lines.
