Biden and Beyond: The United States Rethinks South Asia captures the significant transitions unfolding in the US policy towards South Asia. Developed across two administrations, led by Donald Trump and Joe Biden, the US' South Asia policy has moved away from more than four decades of focus on Afghanistan, especially after the military withdrawal from Afghanistan in August 2021, to now viewing the region through the Indo-Pacific prism. The military withdrawal has also undermined the US' long-standing strategic partnership with Pakistan that was viewed as the frontline state in dealing with the turmoil in Afghanistan. This has substantially altered Washington's geopolitical perspective of the South Asian subcontinent. Furthermore, the rising concerns in Washington on China have seen the formulation of an Indo-Pacific strategy that has elevated India to the top of US strategic priorities. The deepening tensions between China and the US, as well as between Beijing and Delhi, have set the stage for a new strategic partnership between Washington and Delhi. Amidst Washington's competition with Beijing, the Himalayan region girding the underbelly of China has acquired an importance of its own. The maritime perspective of the US has also raised the value of the subcontinent's waters and provided an incentive for Washington to turn new attention to the strategic islands of the Maldives and Sri Lanka. Taken together, these factors presage a transformation in the interaction between the US and the South Asian subcontinent in the coming years. This book, hence, brings into the conversation these recent changes and sheds new light on contemporary US-South Asia relations.
