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?

A newly drafted United States nuclear strategy that has been sent to President Trump for approval would permit the use of nuclear weapons to respond to a wide range of devastating but non-nuclear attacks on American infrastructure, including what current and former government officials described as the most crippling kind of cyberattacks.

North Korea’s 3,000 to 6,000 hackers and the 10 to 20 percent of its military budget going toward online operations mean the country’s cyberthreat to the United States stands only behind that of China, Russia and Iran. If the current tensions continue to escalate, could the United States or North Korea use their cyber-capabilities as a “force multiplier” to conventional military systems?

"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."

"...Germany has an opportunity at the Washington summit — and thereafter — to step up and lend non-American leadership to the problem. Recognizing that in many of the world's capitals the threat of nuclear terrorism is not yet being taken seriously, and when in some of them the very notion is even considered an American pretext for an entirely different, potentially hostile political agenda, non-American leadership is most urgently needed."

There is much to learn from the British: their reticence about disclosing details, their clear expertise in human intelligence, their non-hysterical reaction to very real threats. But how we deal with our immigrant and domestic populations is certainly not one of them.
