As Australian Defence Minister Richard Marles arrives in the United States, a prominent Washington think tank has called for a comprehensive overhaul of the AUKUS security partnership, particularly focusing on Pillar II. The think tank recommends prioritizing autonomy, long-range strike capabilities, and integrated air defense within the trilateral alliance involving the US, UK, and Australia. The AUKUS submarine program remains critical to regional security for Australia, but experts emphasize the need for better progress measurement and practical implementation. The partnership is described as being at an inflection point, with all three countries urged to intensify efforts to ensure its success. Meanwhile, Marles has not yet confirmed a face-to-face meeting with his US counterpart amid some confusion within the Trump administration regarding the meeting's circumstances. Additionally, Marles is scheduled to visit Japan early next month to inspect one of the Maritime Self-Defense Force's Mogami-class frigates.
