The Second Nuclear Age

NEW HAVEN – North Korea’s launch of a long-range missile in mid-December was followed by a flurry of global condemnation that was almost comical in its predictability and impotence. But the launch underscored a larger reality that can no longer be ignored: the world has entered a second nuclear age. The atomic bomb has returned for a second act, a post-Cold War encore. This larger pattern needs to be understood if it is to be managed.

The contours of the second nuclear age are still taking shape. But the next few years will be especially perilous, because newness itself creates dangers as rules and red lines are redefined. This took at least ten years in the first nuclear age, and this time may be no different.
