Samir Paul Kapur: The Delhi-born diplomat steering America’s South Asia policy

(Jun 23, 2026) Samir Paul Kapur is the Indian-origin academic-turned-diplomat appointed by President Donald Trump as the US Assistant Secretary of State for South and Central Asian Affairs. He has been serving in his role since October 2025. The diplomat was in New Delhi last weekend for a series of high-level engagements in his second official visit to India in three months, underlining just how central India is to his mandate.

In his role, Kapur shapes policy across a vast region spanning India, Pakistan, Afghanistan and Bangladesh in the south, all the way to the landlocked republics of Kazakhstan, Uzbekistan and Tajikistan in the heart of Central Asia. 

On 10 June 2025, at his confirmation hearing before the Senate Foreign Relations Committee, Kapur had spoken with characteristic directness and candour about his roots that resonated with Indians who were watching. “I can’t avoid the feeling of having come full circle,” he told senators.

I was born in New Delhi, to an Indian father and an American mother. Although I visited India often during my childhood, I grew up in the United States as a thoroughly American kid, never imagining that my career would someday return me to the place where I was born.

That arc from visits to Delhi during childhood steeped in two cultures, to decades of scholarship on the very region he was born into, to the upper echelons of American diplomacy, defines one of the most compelling Indian-origin stories in Washington today.

A Delhi beginning, an American life

Kapur was born in New Delhi to an Indian father and an American mother, but grew up in the United States. He travelled to India frequently during his childhood and developed an interest in researching it academically. That early, repeated exposure to India planted seeds that would eventually shape an entire scholarly career, and ultimately, a diplomatic one.

He completed his Bachelor’s degree at Amherst College in Massachusetts, and his PhD at the University of Chicago. His doctoral research drew him deeper into the complexities of South Asian security, and he never looked back. What began as intellectual curiosity evolved into a life’s calling spanning classrooms, think tanks, government corridors and, now, the State Department.

From the classroom to the corridors of power

Before entering public service, Kapur was a Professor of National Security Affairs at the Naval Postgraduate School in Monterey, California, where he focused on deterrence theory, nuclear strategy and Indo-Pacific geopolitics. He had earlier taught at Claremont McKenna College and Stanford University, and also ran US-India strategic dialogues for the Department of Defense. It has been a  thread of sustained, institutionalised engagement with India that would long predate his diplomatic appointment.

His academic output is formidable. Kapur is the author of Jihad as Grand Strategy: Islamist Militancy, and National Security, and the Pakistani State (Oxford University Press) and Dangerous Deterrent: Nuclear Weapons Proliferation and Conflict in South Asia (Stanford University Press). He is also the co-author of India, Pakistan, and the Bomb: Debating Nuclear Stability in South Asia (Columbia University Press). His work has appeared in leading academic journals such as International Security, Security Studies, Asian Survey and Washington Quarterly, as well as in outlets including the Wall Street Journal and The National Interest.

His first brush with the State Department came between 2020 and 2021, when he served on the Policy Planning Staff, working on South and Central Asia, Indo-Pacific strategy and US-India relations. That stint gave him an insider’s understanding of the policy machinery he would eventually be asked to lead.

The Trump nomination and a landmark confirmation

In February 2025, President Donald Trump nominated Kapur to serve as Assistant Secretary of State for South and Central Asian Affairs. The nomination drew immediate attention  not only for the geopolitical weight of the portfolio but also for what it represented. An Indian-origin scholar was being handed stewardship of Washington’s most consequential regional relationship.

On the relationship between the country of his birth and the country he serves, Samir Paul Kapur has been clear.

The United States and India share a host of common interests, ensuring a free and open Indo-Pacific region, which is not dominated by China; expanding bilateral trade, building our economic relationship so that it is more symmetrical and profitable; facilitating technology sharing and innovation; and ensuring access to the energy necessary to fuel our economies.

He was sworn in as Assistant Secretary on 22 October 2025. His portfolio covers US diplomatic engagement and strategic partnerships across 13 countries including India, Pakistan, Afghanistan, Bangladesh, Nepal, Sri Lanka, Bhutan and the five Central Asian republics.

Back to his birthplace on official business

Speaking at the India-US Forum hosted by the Ananta Aspen Centre on 19 June 2026, alongside External Affairs Minister Dr S. Jaishankar and Member of Parliament Shashi Tharoor, Kapur engaged with the full sweep of Indo-US relations in a setting built for exactly that kind of high-level exchange.

He also met senior representatives from Boeing, Lockheed Martin and GE Aerospace to explore commercial opportunities in civil aviation. “American innovation and private sector participation are making the US, India and the region more prosperous and secure,” he said following that meeting.

Separate engagements with the US-India Strategic Partnership Forum and AMCHAM India focused on trade, energy and critical minerals — sectors that both governments see as the next frontier of bilateral cooperation. A closed-door USISPF session with leaders from India’s critical minerals sector further underlined the growing strategic importance of supply chain integration to the partnership.

A circle completed

What distinguishes Samir Paul Kapur from many in his position is the texture of his India connection, which is not merely professional. It is personal, familial and intellectual all at once. Family roots shaped the questions he chose to ask, the books he chose to write and, ultimately, the role he chose to accept.

For the Indian diaspora, his ascent carries a particular resonance. It is a reminder that the passage between two cultures, and the hyphen in Indian-American need not be a point of tension. In Kapur’s case, it became the very source of his authority. Born in Delhi, shaped by America, he now stands at the intersection of both, and the view from there has never been more consequential.
