Why have states throughout history regularly underestimated dangers to their survival? Why have some states been able to mobilize their material resources effectively to balance against threats, while others have not been able to do so? The phenomenon of "underbalancing" is a common but woefully underexamined behavior in international politics. Underbalancing occurs when states fail to recognize dangerous threats, choose not to react to them, or respond in paltry and imprudent ways. It is a response that directly contradicts the core prediction of structural realism's balance-of-power theory--that states motivated to survive as autonomous entities are coherent actors that, when confronted by dangerous threats, act to restore the disrupted balance by creating alliances or increasing their military capabilities, or, in some cases, a combination of both. Consistent with the new wave of neoclassical realist research, Unanswered Threats offers a theory of underbalancing based on four domestic-level variables--elite consensus, elite cohesion, social cohesion, and regime/government vulnerability--that channel, mediate, and redirect policy responses to external pressures and incentives. The theory yields five causal schemes for underbalancing behavior, which are tested against the cases of interwar Britain and France, France from 1877 to 1913, and the War of the Triple Alliance (1864-1870) that pitted tiny Paraguay against Brazil, Argentina, and Uruguay. Randall Schweller concludes that those most likely to underbalance are incoherent, fragmented states whose elites are constrained by political considerations.

In Between Threats and War: U.S. Discrete Military Operations in the Post-Cold War World, author Micah Zenko presents a new concept to capture and illuminate the phenomenon: "Discrete Military Operations."

A hostage rescue specialist is on the trail of a homegrown terrorist organization in this thriller by the New York Times bestselling author. When a cult-like paramilitary group decides to make its deadly presence known, the first victims are random. Ordinary citizens going about their lives in Washington, D.C., are suddenly fired upon at rush hour by unseen assassins. Caught in the crossfire of one of the attacks, rescue specialist Jonathan Grave spies a gunman getting away—with a mother and her young son as hostages. To free them, Grave and his Security Solutions team must enter the dark heart of a nationwide conspiracy. But their search goes beyond the frenzied schemes of a madman's deadly ambitions. This time, it reaches all the way to the highest levels of power…

From the universally acclaimed author of The Remains of the Day comes a mesmerizing novel of completely unexpected mood and matter--a seamless, fictional universe, both wholly unrecognizable and familiar. When the public, day-to-day reality of a renowned pianist takes on a life of its own, he finds himself traversing landscapes that are by turns eerie, comical, and strangely malleable.

This innovative argument shows the consequences of increased aversion to international war for foreign and military policy.

The balance of power principle has been central to both the study and practice of international politics for over 300 years. It has guided governments in the conduct of foreign policy and provided a structure for explanations of some of the recurring patterns of international relations. This study examines the various meanings given to the balance of power over the centuries and traces the historical evolution of its theory and practice through steadily more complex forms. It describes the balance principle in practice, both as a guiding light of national foreign policies and as a structural explanation of how the international system operates. The reader is provided with an understanding of the various meanings of the balance principle and the key thinkers and politicians who have influenced its development. The text presents the essence of arguments concerning the morality of the principle as a foreign policy guide and its value as a structural explanation of the fundamental reality of international relations.
