The computing and digital revolutions have created new tools and capabilities that are challenging the liberal world order. If the Cold War was an era of static state superpowers, modern computing gives not only developed states but even a moderately trained rebel group their own superpowers: to teleport their presence around the globe, move vast sums of money instantly, and make evidence vanish. From Wikileaks to the hacking of elections, headlines across the democratic world have highlighted transnational cyber-enabled crime, violence and polarization. The goal of this workshop is to bring scholars together from a variety of backgrounds to discuss whether current concepts and theories are sufficient to suggest solutions to these cyber dilemmas, particularly for open liberal democracies. Topics would include current and emerging cyber security challenges like hacking, election manipulation and disinformation, cyber crime, online radicalization, as well as topics related to domestic and international trust and distrust, including intelligence cooperation, surveillance, repression, leaking and whistle-blowing, evolving alliance commitments and rivalries. One cross-cutting theme that will be of particular interest is how the tools and technologies maintained by international cooperation and liberal societies, such as the internet, open source software and free social media, are being used to undercut governance and bipartisanship; and what can be done about it.
