Yet, to many American policymakers, Asia is still a “black box.” Americans are unfamiliar with Asian history in general, and more specifically, American policymakers are not fully aware that the Japanese state identity is the primary determinant of Japan’s vital national interests and therefore drives its grand strategic choices. Only by grasping this identity from a macro-historical and geo-political perspective, as fully explored and elaborated in this paper, can the United States secure Japan as a reliable partner and to effectuate a more durable bilateral alliance. If the U.S. fails to follow such an approach, or if it achieves only a superficial understanding, it will alienate Japan and will bring about the dissolution of the indispensable bilateral alliance.
