After the Cold War, the system of international relations entered a new era. With the bipolar world order broken, countries started a complex conflict and cooperation process to establish a new multipolar world order. Stemming from basic strategic interests, these countries have to make adjustments and supplements foreign strategic position to win favorable positions to their interest in the international system. The similarity and/or differences in interests, ideological perspective, history, culture ... between countries are always a major factor and dominant impact issues of cooperation and conflict. Besides the efforts to maintain peace and expand cooperation for development, the world witness many international conflicts in both large scale and small scale. Therefore, when talking about the trend of peace and cooperation it is impossible to ignore the impact and influence of current international conflicts as well as the possibility of new conflicts future.
Meanwhile, the world is further shaken by a series of regional conflicts, internal conflicts. From 1945 to date, although there is no world wars occurred, but there are more than 60 small and medium sized wars with conventional weapons and high-tech weapons. It seems that there is a development in the trend of conflicts, not cooperation.

For Realists, war is the product of the states’ competition for power; therefore, war is unavoidable. On the other hand, Idealists believes that war is the product of socio-economics inequality and the interest of the monarchy. It is difficult to address a single cause of war. However, in the world of increase globalization and complex interdependence, the root of conflicts also becomes extremely complicated to identify. In the new world order, there are certainly strong countries and weak ones. However, the new multipolar world order has created a space for even the weak power to have leverage over the stronger one. In this paper, I argue that the lack of interdependent in the perceivable interests of states, whatever those interests maybe is the leading cause for conflicts. In this case, the interest of state is not necessarily power and/or wealth but any other interests that are perceivable by the governing body of the states.
The states, in any school of thoughts, are seen are an interest-seeking entity with the ability to rationalize their actions and weighing the gains and costs of such action. The actions of such states often set the playing ground for international politics which set the structure for international politics. The Realists often assume that the international system is anarchic in nature with no order or an authoritative government. Because of this anarchical nature, conflict is unavoidable. Kenneth Waltz states that “Among men as among states, Anarchy, or the absence of government, is...
