The U.S. officials interviewed for this study see little chance of an immediate improvement in U.S. relations with Japan over the next year. Trends in the United States and Japan in recent years have led to deepening U.S. frustrations, especially over economic issues. These developments have combined with fundamental changes (notably the collapse of the USSR) affecting U.S.-Japanese political-military ties to lead many U.S. officials to question the allocation of costs and benefits in the U.S.-Japan relationship and to press for arrangements that will alter the allocation in the interests of the United States. U.S. officials assume that their Japanese counterparts are undertaking similar reassessments.
