The world system has undergone a large-scale transition for the last two decades. The ultimate victory of the United States declared after the collapse of the Soviet Union in 1991 lasted only for a decade. In spite of giving an effective answer to the Sept. 11 terrorist attacks, the U.S. has been unable to maximize its national interests at the global scale and provide international peace and stability.

Today, we are living in a systemic transition period in which the world is experiencing an international systemic crisis. Deep uncertainty and instability have been dominating the global system. The rivalry between global powers has been intensifying every day. Unfortunately, there is no established international order and no stable relationship between even members of the same alliance. Most hostilities and friendships are temporary; relations between any two states can change quickly.
