This study traces the historical evolution of regional security frameworks and the need for a NATO-like alliance in the Indo-Pacific. It evaluates past multilateral defense initiatives, explores ways to adapt NATO’s model to the Indo-Pacific, and assesses political willingness, defense commitments, and nuclear burden-sharing among its proposed core members—Japan, South Korea, Australia, and the United States. Additionally, it outlines implementation strategies and key challenges, arguing that the IPTO is essential for strengthening deterrence, ensuring regional stability, and countering growing security threats.
As the limitations of the U.S. “hub-and-spoke” alliance system become more apparent, the creation of the IPTO marks a necessary evolution in Indo-Pacific security at a pivotal moment for the United States and its regional Allies.
