A growing number of pro-American foreign and defense policy pundits in Seoul are tending to be too optimistic over the US-South Korean defense relationship, as if the relationship couldn't be better. But trouble could be looming. The alliance cannot endure another several decades in its current form. A new form of security needs to be created as soon as possible, working for the defense and expansion of a more stable order in Northeast Asia. That new security forum, of course, must deal with China and North Korea logically in their place. One of the Lee government's central strategic tasks is to set up detailed and strategic plans toward the current Korea-US alliance and to forge a more balanced order in the region. A taster's choice moment for the alliance is over.
