Realist scholars have long debated the question of how much power states need to feel secure. Offensive realists claim that states should constantly seek to increase their power. Defensive realists argue that accumulating too much power can be self-defeating. Proponents of hegemonic stability theory contend that the accumulation of capabilities in one state can exert a stabilizing effect on the system. The three schools describe different points along the power con­tinuum. When a state is weak, accumulating power increases its security. This is approximately the situation described by offensive realists. A state that con­tinues to accumulate capabilities will eventually triggers a balancing reaction that puts its security at risk. This scenario accords with defensive realist as­sumptions. Finally, when the state becomes too powerful to balance, its oppo­nents bandwagon with it, and the state’s security begins to increase again. This is the situation described by hegemonic stability theory. These three stages delineate a modified parabolic relationship between power and secu­rity. As a state moves along the power continuum, its security increases up to a point, then decreases, and finally increases again. This modified parabolic re­lationship allows scholars to synthesize previous realist theories into a single framework.

Today, territorial ownership of states is essentially fixed, in marked contrast to earlier periods in history. This change has affected states in two very different ways. In regions in which most states are socio-politically strong, fixed territorial ownership is a blessing. It enhances peace, stability, and cooperation between states. In regions in which most states are socio-politically weak, however, fixed territorial ownership is largely a curse. It perpetuates and exacerbates states' weakness, and contributes to internal conflicts that often spill overacross international borders.

Rotberg argues that failing states are a particular worry to the security of the twenty-first century.
