The Alliance faces an increasingly severe strategic and nuclear threat environment. The Government of Japan and the Government of the United States of America are committed to reinforcing extended deterrence in order to promote regional stability and deter the outbreak of conflict.
Based upon accumulated discussion primarily through the Extended Deterrence Dialogue (EDD), the Governments of Japan and the United States have formulated the Guidelines for Extended Deterrence. This document reinforces the Alliance’s existing consultation and communication procedures related to extended deterrence. The Guidelines also address strategic messaging to maximize deterrence and enhance measures for U.S. extended deterrence, bolstered by Japan’s defense capabilities.
The Alliance will continue to explore how best to ensure extended deterrence is strong and credible.
