Contemporary regional issues in Asia and the Pacific have diversified to include non- traditional security concerns. This has triggered a call to revisit the US “hub-and-spoke” approach for solutions. The increased importance of Asian states in global affairs adds more urgency to the need to complement existing post-World War II diplomatic structures with an “Alliance Caucus” between the US and its Alliance partners. This project explores the need for a parallel structure (informal or formal) alongside state-to-state meetings to address common concerns that are beyond the scope of official agendas.
