All #NPT States Parties should be concerned with Iran’s flagrant violation of the treaty. To defend the foundation of the nonproliferation regime, all NPT States Parties should use the RevCon to defend the treaty and the safeguards system. The time is now, and the need is urgent.

On April 28, @StateACN Assistant Secretary Dr. Christopher Yeaw delivered the U.S. national statement to the #NPT Review Conference. Now is the time to ensure the NPT regime is prepared to face the challenges of today and those of tomorrow. state.gov/wp-content/upl…

His Majesty King Charles’s historic gift of the ship’s bell from the HMS Trump links the past to the future. HMS Trump served during World War II in the UK’s 4th Submarine Squadron based in Perth, Australia — the location of today’s Submarine Rotational Force - West. From Pacific War heroics to joint submarine rotations in the face of new challenges, the AUKUS bond is deeper than ever. @UKRoyalNavy_ @Australian_Navy
