This chapter searches for a unification model for Korea assuming a big bang implodes or explodes on the Korean Peninsula sooner or later. Amidst the prolonged deadlock of the six party talks, Pyongyang insists to hold a bilateral talks with Washington while the latter says it must be discussed in the framework of six countries talks. The UN General Secretary addressed on July29, 2009 in New York that he would visit Pyongyang to bridge US-North Korea’s bilateral relations, which is only likely to make Korean unification cross the river of no return for long periods to come. The road to Korean unification cannot be also easy as long as four big powers (China,Japan,USA and Russia) perceive respectively as if a unified Korea may contribute to disturb the balance of power among themselves. As an alternative to disengage the four powers from their perceived stakes in Korea without fear that the balance of power in the region will be tipped against any of them, a “temporal neutralization” for Korea is proposed by suggesting that it can serve as a beneficial institution to all concerned parties in the region. Neutrality is offered to overcome existing international power politics surrounding the peninsula.When the world develops into more peaceful and cooperative future beyond any further ideological and military stripe,Korea may no longer be of concern to others for its siding in politics.Under the current circumstance, however, the idea of a unified “neutral Korea” can only likely buy all round supports from its neighbors.
