State Power - Security Mechanism Of Competition: A Realistic Theoretical Perspective

In international politics contention, the power is considered as the ultimate means to guarantee the national security. However, between power and security dialectical relations, power agglomeration's security effectiveness has caused the opposition between offensive realism and the defensive realism. Defensive realism believes that power is means and the security is purpose. Power and security may be inconsistent and even appear the situation of two-dual opposition. The pursuit for power will harm national security in these situations. Thus the country will be impossible to pursue the authority maximization as the goal. But offensive realism acknowledge dichotomy which power and security are recognized as means and purpose. And power is the only reliable method to maintain the security; the power and security has same significance status, and pursuing safety meant to pursue power; and vice versa. The degree of national security and relative status in international system is direct proportion. The most reliable way to secure country is power maximization, and ideal result is to obtain the hegemony; the hegemony status will guarantee the national security maximization. Offensive realism points that the hegemony status means the most exciting enticement for great powers which take the security as the priority target! The security dilemma caused by anarchy and self-service logic is the internal power mechanism.
