WASHINGTON — High-level officials from the United States and Japan convened at the State Department on February 18, 2026, for the latest Extended Deterrence Dialogue (EDD). The bilateral talks underscored a deepening strategic partnership aimed at countering regional threats and reinforcing the “nuclear umbrella” protecting Japan.
The dialogue was co-chaired by the U.S. Departments of State and War and Japan’s Ministries of Foreign Affairs and Defense. Senior representatives from the U.S. Strategic Command, U.S. Indo-Pacific Command, and both nations’ Joint Staffs were also in attendance.
Commitment to “Full Range” of Defense Capabilities
A primary focus of the EDD was advancing the shared vision of President Trump and Prime Minister Takaichi to modernize the alliance’s response capabilities. In a clear signal to regional adversaries, the United States reaffirmed its ironclad commitment to the defense of Japan.
Specifically, the U.S. delegation emphasized that this protection includes the “full range” of American military assets, explicitly mentioning nuclear capabilities. In turn, Japan reaffirmed its support for U.S. operations essential to maintaining regional peace, noting that Japan’s increasing investments in conventional defense are critical to reinforcing deterrence by denial.
Addressing China’s Nuclear Buildup and Russian Noncompliance
The delegations held extensive discussions on the evolving global threat landscape, specifically highlighting:
-
China: The rapid, opaque, and destabilizing expansion of China’s nuclear arsenal and testing programs.
-
Russia: Russia’s historical noncompliance with international arms control treaties.
-
North Korea (DPRK): The continued advancement of the DPRK’s nuclear and missile programs, with both nations reiterating their demand for complete, verifiable denuclearization.
The United States reiterated the urgent need for multilateral strategic stability talks. Japan expressed support for the U.S. goal of achieving a more robust arms control agreement, emphasizing that any future framework must involve both Moscow and Beijing to be effective.
Strengthening Communication and Coordination
The talks also focused on operationalizing the U.S.-Japan Guidelines for Extended Deterrence. Both sides agreed to enhance strategic messaging, improve crisis communications, and tighten coordination to ensure U.S. extended deterrence remains credible and responsive.
Concluding the session, the delegations conducted a tabletop exercise to simulate real-world crisis scenarios, testing the interoperability of the two nations’ defense apparatuses under pressure.
