If one state’s influence increases, it poses a certain kind of challenge the stability of the other power, which assumes that it would confront my state in the future and challenge security and survival with increasing power. To eliminate this risk, great powers interfere, thwarting each other’s efforts so that they can not create any kind of problem to the interests. Great powers also work together to pursue mutual interest and shared goals in different fields. One does not trust others’ ambitions amid itself since every state in international politics struggles to maximize its own security and minimize potential or long-term threats at others’ expense. The cooperation is often limited to a point where there comes a national security matter.
