Prime Minister Abe Shinzō's stunning return to power in the December 2012 landslide election victory, and the consolidation of his leadership in a repeat victory in December 2014, has heralded the resurgence for Japan of a more assertive, high-profile, and high-risk, foreign and security policy. However, as Japan's Foreign and Security Policy Under the ‘Abe Doctrine’ suggests, Abe's status as an arch-‘revisionist’ ideologue, combined with the track record of his first administration in 2006-2007, made clear that he would move aggressively to shift Japan towards a more radical external agenda—characterized by a defense posture less fettered by past anti-militaristic constraints, a more fully integrated US-Japan alliance, and an emphasis on ‘value-oriented’ diplomacy with East Asian states and beyond. Indeed, Abe's diplomatic agenda has been so distinctive and forcefully articulated in past years that it might be labeled as a doctrine capable of rivaling, and even of displacing, the doctrine of Prime Minister Yoshida Shigeru that has famously charted Japan's entire postwar international trajectory. In contrast to Abe's more muscular international agenda, the so-called ‘Yoshida Doctrine’, forged in the aftermath of total defeat in the Pacific War, has long emphasized for Japan the need for a pragmatic and low-profile foreign policy, a highly constrained defense posture, reliance but not over-dependence on the US-Japan security treaty, and the expedient rebuilding of economic and diplomatic ties with East Asian neighbors.
