The beginning stage of the relation was zero-sum game. If one was advanced from the choice, the other one lost and made zero total payoffs. This phenomenon happened because two countries did not have common gains. Since there was not common social welfare, each country did not corporate and they could only compete and confront. The distrust between countries resulted confrontation and opposition. It could be a deer hunting game model after the self-destruction of Soviet Union and 88’ Seoul Olympics, but they still had lack of trust and North Korea worsened the relationship because of the nuclear weapon.

Considering their different aspect and historical scars, the relation could not get better in short time period. Even though there were some interactions and conferences, continuous government failing policies against North Korea gave disrespect and lack of confidence to South Koreans. This current situation could be expressed in Prisoner’s dilemma. Each country had realized that they could benefit both if they corporate. However, they were in competing mode for a long time, they acted more sensitively in relative gains than in absolute gains. Even though one country was gained from a choice, if the other country was better off, they might not corporate each other.

Even though both countries are defecting each other, the two countries could not help but corporate each other in long term view. Interactions between two countries in sports, economics, and politics would destroy the difficult differences and they would corporate eventually. Once they corporate and actually got benefited, the distrust would minimized and the chance to become worsen-relation would be low. On top of it, if the corporation was maintained, the unification could possibly achieve within close future.

This system could be expressed in Deer Hunting model. This model is ‘win-win’ game and both countries get paid off the most if they both corporate. The globalization results unlimited competition and the only thing to survive from the competitive market is to corporate. If one thinks a country as an enterprise, the diplomatic relations between two countries could be described as game theory. In fact, every diplomatic relation is game theory and each country, or each player, is trying to maximize its payoff from the game.
