Nuclear Issues

Stephen Walt writes that the future will be determined by a handful of big questions: What is China's future trajectory; How good are America's cybercapabilities; What's going to happen to the EU; How many states will go nuclear in the next 20 years; and Who will win the debate on U.S. grand strategy?

"Cyber war, though only incipient at this stage, is the most dramatic of the potential threats. Major states with elaborate technical and human resources could, in principle, create massive disruption and physical destruction through cyber attacks on military and civilian targets. Responses to cyber war include a form of interstate deterrence through denial and entanglement, offensive capabilities, and designs for rapid network and infrastructure recovery if deterrence fails. At some point, it may be possible to reinforce these steps with certain rudimentary norms and arms control, but the world is at an early stage in this process."
