It is tempting to characterize the recent round of North Korea missile and nuclear tests as only the latest example of the provocative behavior of its brash young leader, Kim Jong Un. A simultaneous launch of three medium-range missiles, mounted on mobile launchers, was defiantly timed to coincide with China’s hosting of the G20 summit in Hangzhou. And the latest nuclear test, the fifth carried out by North Korea, seemed designed to assert its status as a nuclear weapons power ahead of the U.S. presidential vote, Sneider writes.
