"While journalists have provided a number of histories of the events that led to bin Laden's death, the purpose of this analysis is to examine White House decisionmaking for lessons that can be applied to future foreign policy challenges."

In a TIME magazine cover story, Belfer Center Director Graham Allison writes about decisions behind the raid that led to the death of Osama bin Laden. Allison, whose analysis is the result of more than 100 hours of interviews, is author of the prize-winning analysis of the 1971 Cuban Missile Crisis, Essence of Decision.

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.
