Middle East & North Africa

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?

When it comes to cyberweapons, America is an elephant and Iran is a flea. Still, a flea can be a persistent nuisance, especially for the unprotected.

As President Trump increasingly boxes in Tehran, U.S. allies should be worried about the potential for a devastating cyberattack from the Islamic Republic.

Regardless of the innovations that lie ahead, technology by itself will neither doom nor rescue the world. Responsibility for our fate, for better or worse, will remain stubbornly human.

In March, the Justice Department unsealed an indictment against seven Iranians for hacking the U.S. financial sector and a dam in New York. In doing so, it also clarified what information security officials have argued for years: that the vast majority of hacks exploit known vulnerabilities.

"In little more than a generation, the Internet has become the substrate of the global economy and governance worldwide. Several billion more human users will be added in the next decade, as will tens of billions of devices, ranging from thermostats to industrial control systems (the 'Internet of Things'). All of this burgeoning interdependence implies vulnerabilities that governments and non-governmental actors can exploit. At the same time, we are only beginning to come to terms with the national-security implications of this. Strategic studies of the cyber domain resemble nuclear strategy in the 1950s: analysts are still not clear about the meaning of offense, defense, deterrence, escalation, norms, and arms control."

"As for the perceived loss of America's much-vaunted superpower status, we simply need to come to terms with the changing reality of international relations, and accept that the United States will have to work with others to achieve its global aims. The changes of a global information age mean that even the world's only superpower can't go it alone."
