This book is a collection of the author's blogposts from 2008–2013, almost all of them from the Huffington Post and reposted on the website of the Harvard Kennedy School's Belfer Center for Science and International Affairs by the International Security Program. Most of them deal with the author's particular area of expertise, from Morocco to Bangladesh, but also with Europe and transatlantic issues. A few are film reviews, and others deal with the U.S. Presidency and the Congress.

Is religion a force for good or evil in world politics? How much influence does it have? Despite predictions of its decline, religion has resurged in political influence across the globe, helped by the very forces that were supposed to bury it: democracy, globalization, and technology. And despite recent claims that religion is exclusively irrational and violent, its political influence is in fact diverse, sometimes promoting civil war and terrorism but at other times fostering democracy, reconciliation, and peace. Looking across the globe, the authors explain what generates these radically divergent behaviors.

In Weapons of Mass Migration, Kelly M. Greenhill offers the first systematic examination of this widely deployed but largely unrecognized instrument of state influence. She shows both how often this unorthodox brand of coercion has been attempted (more than fifty times in the last half century) and how successful it has been (well over half the time). She also tackles the questions of who employs this policy tool, to what ends, and how and why it ever works. Coercers aim to affect target states' behavior by exploiting the existence of competing political interests and groups, Greenhill argues, and by manipulating the costs or risks imposed on target state populations.

The spread of nuclear weapons is one of the most significant challenges to global security in the twenty-first century. Limiting the proliferation of nuclear weapons and materials may be the key to preventing a nuclear war or a catastrophic act of nuclear terrorism. Going Nuclear offers conceptual, historical, and analytical perspectives on current problems in controlling nuclear proliferation. It includes essays that examine why countries seek nuclear weapons as well as studies of the nuclear programs of India, Pakistan, and South Africa.

"Concern over nuclear proliferation is likely to increase in the coming years. Many observers believe that the spread of nuclear weapons to one or two more states will trigger a wave of new nuclear states. More states may turn to nuclear power to meet their energy needs as other sources of energy become more costly or undesirable because they emit carbon that contributes to global climate change. As more nuclear reactors are built, the world's stock of nuclear expertise and fissionable materials is likely to grow."

"In How the Weak Win Wars, Arreguin-Toft means to convince the reader that when the very strong meet the weak in asymmetric armed conflict, strategy matters more than power. Despite minor excursions in his conclusions, he achieves this goal through expert scholarly analysis and a writing style that elucidates complex topics with facility. His work is extremely relevant in the current geopolitical context and serves as a warning to US policy makers to get military strategy right, regardless of relative power. Arreguin-Toft's argument makes perfectly clear the perilous consequences of neglecting the importance of strategic interaction."

The threat of terror has given the problem of failed states an unprecedented immediacy and importance. In the past, failure had a primarily humanitarian dimension, with fewer implications for peace and security. Now nation-states that fail, or may do so, pose dangers to themselves, to their neighbors, and to people around the globe. The contributors to this volume develop an innovative theory of state failure that classifies and categorizes states along a continuum from weak to failed to collapsed.
