This book discusses the partnership between United States and India in the Indo-Pacific region, which also serves as an engine for the Quad alliance of US, India, Japan and Australia. It investigates the multilateral efforts taken by the QUAD and its effects on changing, reforming or establishing a new regional security complex against China in the Indo-Pacific.

The theory employed by the author is based on a novel construct of Heterarchical Regional Security Complex (HRSC), which refers to a de-centralized principle of power distribution i.e., power is not concentrated in a particular element rather it is diffused within the entire structure. When merged with the Regional Security Complex (RSC) Theory, it presumes the creation of such a security complex in which all members have roughly equal power. This book unravels how the QUAD can operate as a HRSC in balancing against China's growing hold in the region. It is supplemented by the Balance of Threat framework to discuss the functioning of QUAD from a minilateral perspective with a heterarchical overlay. Besides QUAD, this book also focuses on the blooming partnership between United States and India since the turn of the century (2007-2020).

This book will be beneficial for researchers interested in International Relations, Asian Politics, Regional Security, and Indo-Pacific studies.
