James Na on North Korea's Missile Threat

From Real Clear Politics:

That leaves, as always, Beijing. To say that China is embarrassed by North Korea's latest provocation is an understatement. Thus it is now the time to press Beijing hard, for once. North Korea's ballistic missile and nuclear threat would not be where it is today were it not for Beijing, and the U.S. should finally make China take responsibility -- by agreeing to the quarantine. And the United States should make the continued Sino-American economic relationship contingent on China acting like a mature great power by exercising this responsibility.

Ultimately, China's economic relationship with the U.S. is far more important for China's economic growth and political stability than continuing to protect North Korea's arsenal. The choice ought to be, thus, very clear for China's leaders -- provided, of course, that Washington presents Beijing with the choice.

Will the Bush administration, at last, exercise this potent lever to contain North Korea's nuclear and proliferation threat? Or will the pro-China business lobby again trump national security and constrain the administration into rhetorically magnificent, but utterly ineffectual, symbolic gestures?
