Hotlines for the Digital Age: Improving communications in cyber-generated national security crises
What do countries that don’t have regular high-level security communications pathways do when their critical digital infrastructure is under cyber attack, and the cyber attack appears to be coming from the territory of a country on the other side of the globe? An ongoing negotiation convened under the United Nations First Committee is building a structure to make clear and urgent communication on cybersecurity incidents accessible to every government.

The Role of Crisis Communications in the Russo-Ukrainian War
The Russo-Ukrainian War has not been tempered nor solved by the existence of crisis communications between nuclear weapon states. However, the existence of the senior and tactical level deconfliction lines may continue to play a role in limiting escalatory action between these adversaries.

Report
Building Communications Norms Across Nuclear C2
Dr. Salma Shaheen stresses the importance of establishing new norms, constructing new practices, and securing reliant communications between nuclear-armed states before a potential crisis. Shaheen reaffirms the need for a direct communication link between global leaders to facilitate quick and efficient communications between nuclear-armed states — a capability she cites as essential for escalation control and nuclear weapons reduction, with a direct impact on crisis aversion and thus global security.

Nuclear Hotlines: Origins, Evolution, Applications
Dr. Steven E. Miller gives an overview of experiences to-date with nuclear hotlines. He reviews the history of the US-Russia hotline, describes the ways that hotlines can be used or misused, and charts how the hotline concept has evolved and propagated to help states manage international crises. Hotlines are important, if imperfect, tools for avoiding nuclear conflict.
