The world has entered a new information age that has transformed the planet into a common space where billions of people can connect and share information on a global scale. Social media platforms constitute a key instrument of this technological revolution. However, they are not merely a way to connect with other people, market business, or promote political campaigns. They can now be used to shape the outcome of elections, battles, and even geopolitics itself. The online world has become a global space of confrontation that we need to better understand, as fights for popularity and perception merge with real world conflicts. P.W. Singer and Emerson T. Brooking’s book, LikeWar, tackles this phenomenon. The International Security Program invites you to a discussion of this critical issue with Dr. Singer and Dr. Kathleen Hicks.
