The chapter examines the constitutional order that emerged in Europe through the quest for digital sovereignty. Drawing on policy documents and an ethnographic investigation of a French diplomatic unit, I explore two problematizations of digital sovereignty. The first, which originates with NATO and the East StratComm task force, is grounded on the assumption of an emerging threat and the constitution of Russia as a common enemy. The idea that Europe must take part in an information war is based on the supposition that a technological arrangement can be stabilized. Along with this, and in reaction to it, the EU has built a problematization of digital regulation processes. A moral economy has been embedded in a regulatory framework, with the understanding that digital service platforms have also become enemy figures. The elicitation of these problematizations introduces a critical perspective on digital sovereignty as a way to define Europe through technologies and knowledge that suppose a common enemy. I call this “constitutionalism through the enemy”.
