The possibility that hackers might break into nuclear command and control facilities, compromise early warning or firing systems, or even cause the launch of nuclear weapons, has become disturbingly real, says Andrew Futter (University of Leicester). While this challenge will impact all nuclear-armed states, it appears particularly acute for the United States and Russia given their large, diverse, and highly alerted nuclear forces. In this new Deep Cuts Issue Brief, Andrew Futter analyzes the dynamics caused by potential cyber insecurity and their impact on arms control and possible future nuclear reductions and offers a number of concrete suggestions on how to address this complex interplay.
