Japan's Security Strategy in the Post-9/11 World

In this book, Daniel Kliman argues that the years following September 11, 2001, have marked a turning point in Japan's defense strategy. Utilizing poll data from Japanese newspapers as well as extensive interview material, Kliman chronicles the erosion of normative and legal restraints on Tokyo's security policy. In particular, he notes that both Japanese elites and the general public increasingly view national security from a realpolitik perspective. Japan's more realpolitik orientation has coincided with a series of precedent-breaking defense initiatives. Tokyo deployed the Maritime Self-Defense Force to the Indian Ocean, decided to introduce missile defense, and contributed troops to Iraq's post-conflict reconstruction.
Kliman explains these initiatives as the product of four mutually interactive factors. In the period after September 11, the impact of foreign threats on Tokyo's security calculus became ever more pronounced; internalized U.S. expectations exerted a profound influence over Japanese defense behavior; prime ministerial leadership played an instrumental role in deciding high profile security debates; and public opinion appeared to overtake generational change as a motivator of realpolitik defense policies.
This book rebuts those who exaggerate the nature of Japan's strategic transition. By evaluating potential amendments to Article 9, Kliman demonstrates that Tokyo's defense posture will remain constrained even after constitutional revision.
