The key to understanding North Korea’s strategy may lie in the recent past of another Asian nuclear state: China.

Mao Zedong’s China began, in the 1950s, as a pariah state, isolated and threatened by the United States. It became, in the 1960s, a rogue nuclear power. And then it rose, through the 1970s, into an accepted member of the international community, embraced even by its onetime adversary.

North Korea appears bent on following that progression. A nuclear program that can threaten the United States, making war unthinkable, would be only step one — and may, with the missile tests this summer, now be complete.

China ultimately won acceptance by playing the United States against the Soviet Union, not by rattling nuclear sabers. Its size and power also made it impossible for other nations to ignore it, advantages that North Korea lacks.

But North Korea’s desperation, as well as its longtime obsession with China, may have led it to see the possibility, however misguided, of achieving success by following Beijing’s script.
