NOT long ago North Korea-watchers were speculating that the new leader, Kim Jong Un, might prove a moderniser. The path-breaking boy-dictator let himself be seen with his fashionable wife. He actually spoke in public, whereas his late father’s speeches were as rare as a well-stocked Pyongyang supermarket. Lately, though, Mr Kim has reverted to type by prophesying war. Experts fear the North’s Punggye-ri underground complex is about to host a nuclear test. If it does, Mr Kim will inherit the family title of Asia’s pariah-in-chief.
