Speaking on December 24, 2019, Russian President Vladimir Putin marked the deployment of Russia’s first nuclear-capable hypersonic missile system, noting, “Today, we have a unique situation in our new and recent history. [Other countries] are trying to catch up with us. Not a single country possesses hypersonic weapons, let alone continental-range hypersonic weapons.”
The question that is now facing policy makers in Washington, Beijing, London, and elsewhere is whether and how this deployment reshapes strategic stability.
