Since India’s independence, ties with the United States have weathered Cold War–era distrust and estrangement over India’s nuclear program. Relations have warmed in recent years and cooperation has strengthened across a range of economic and political areas.

The Indo-US bilateral ties can be traced from the era of cold war politics. As India was always closer to Soviet Russia, USA had taken a stand against India on various occasions. The entire scope of Indo-USA relations was based upon two contentious issues:

  1. On the issue of Kashmir and USA standing with Pakistan.
  2. On the issue of Nuclear Weapons and technology which India wanted to possess.

From 1947 till early 1960

The Indo-US relation was a victim of Kashmir issue especially when USA and Pakistan signed SEATO (South East Asia Treaty Organisation) and CENTO (Central Treaty Organisation) agreements. In this period the only bright spot between India and USA was the PL-480 programme under which USA supplied foodgrains to India at a very cheap cost.

Another deadly dimension of their bilateral relation was the issue of terrorism, where America was less compassionate on India’s call on cross border terror in Jammu and Kashmir.

Major Events

Let’s discuss India-US relations with the help of a timeline (Some Major Events):

1962 – India, China fight border war:

War breaks out between India and China over a disputed frontier. Prime Minister Jawaharlal Nehru writes to President John F. Kennedy to request support from the United States. Washington supports India in the conflict, recognizing the McMahon line as the border, and provides air assistance and arms. Until the 1965 India-Pakistan War, strategic and military ties between Washington and Delhi remain close.

1971 – India, Pakistan go to war:

India and Pakistan become embroiled in their third conflict as Pakistan descends into a civil war that ends with the creation of Bangladesh, formerly East Pakistan, on December 6. Despite evidence of the Pakistan Army’s violence against its own citizens in East Pakistan, the United States sides with Islamabad, given its mediating role in Nixon’s rapprochement with China. India also signs a twenty-year Treaty of Friendship and Cooperation with the Soviet Union in August, sharply deviating from its previous position of non-alignment in the Cold War.

1974 – India completes first Nuclear Test:

India detonates its first nuclear device, becoming the first nation outside the five permanent members of the United Nations Security Council to have declared nuclear capabilities. The move contributes to a period of estrangement between the United States and India that lasts over two decades.

1978 – US enacts Non-Proliferation Act:

The Carter (the then US President: Jimmy Carter) administration enacts the Nuclear Nonproliferation Act, which requires countries not included in the Nonproliferation Treaty—which includes India—to allow inspections of all nuclear facilities by the International Atomic Energy Agency. India refuses, and Washington ends all nuclear assistance to Delhi.

1984 – Thousand die in Bhopal Leak:

A toxic gas and chemical leak at American-owned Union Carbide Pesticide Plant in Bhopal, India, kills thousands. India unsuccessfully seeks extradition of the company’s chief executive from the United States for criminal prosecution as the death and disability toll climbs to the tens of thousands in the ensuing years. The incident harms U.S.-India relations, and continues to complicate the bilateral relationship years after.

1991 – India launches Economic Reforms:

The government of Prime Minister P.V. Narasimha Rao launches sweeping economic reforms that help expand economic ties with the United States. Finance Minister Manmohan Singh oversees the opening of India’s economy to international trade and investment, deregulation, initiation of privatisation, tax reforms, and inflation controlling measures that catalyze decades of fast growth.

1998 – India tests Nuclear Devices:

The Indian government announces the completion of a series of underground nuclear tests close to the border with Pakistan, surprising U.S. intelligence organizations and raising fears the move could spark a regional nuclear arms race. The tests draw international condemnation and badly damage India’s relationship with the United States. After recalling the U.S. ambassador to India, President Bill Clinton imposes economic sanctions, required under U.S. law.

1999 – Pakistan, India clash in Kashmir:

The 1999 Kargil War witnessed the first ever support of India from the USA especially on the involvement of Pakistan Army in this proxy war. Pakistani forces infiltrate Indian-administered Kashmir. India launches air strikes in return, and armed conflict continues through early July. After President Clinton summons Pakistani Prime Minister Nawaz Sharif to Washington for an emergency meeting, Sharif withdraws Pakistani forces from their positions beyond the Line of Control.

2000 – Bill Clinton visits India:

The then President of USA, Bill Clinton visited India in 2000 and the then Indian PM Atal Bihari Vajpayee stated India-US were Natural Partners.

2001 – US lifts India’s sanctions:

The 9/11 attack on America changed the entire dynamics of the Indo-US bilateral relationship. Terrorism was recognised as a global problem. India supported USA’s war on terrorism, and USA for the first time declared withdrawal of sanctions imposed against India during the Pokharan Nuclear Test of 1998.  

2002 – High technology cooperation agreement:

PM Vajpayee succeeded in signing Indo-USA high technology agreement. Since its formation in 2002, the U.S.-India High Technology Cooperation Group has been a valuable forum for discussing U.S.-India high technology trade and fostering the confidence necessary to facilitate trade in high technology items.

2004 – NSSP (Next Step in Strategic Partnership):

Under NSSP, India and USA agreed to work primarily in the following areas:

  1. Civil Nuclear Cooperation
  2. Space Technology Cooperation
  3. High Technology Cooperation
  4. Missile Technology Cooperation

2005 – Strengthening Bilateral Relations:

  • USA supported India’s quest for nuclear energy.
  • Removed the Nuclear Apartheid (Sanctions).
  • India was offered the membership of the NSG, Australia Group, and the Wassennaar Arrangement.
  • Institutionalize the defence cooperation between the two nations. Such as “Yudh Abhyas” and other defence cooperation.

Bilateral Relations

Bilateral relations between any two countries can be multi-faceted. Let’s discuss India-US relations with reference to some major aspects:

Political

India and USA, both are founding members of the UNO. Both are largest contributors to the UN Peacekeeping Force. USA supports India’s candidature for the permanent seat in UNSC.

Economy

USA is India’s second largest trading partner.

  • USA’s imports from India largely include – cotton, textiles, pearl, gemstones, jewellery and agriculture allied products.
  • India’s imports from the USA include – hardware, civilian air telecommunications, chemicals and fertilizers.

Institutionalisation of India-US bilateral economic cooperation by the creation of US-India Trade Policy Forum. The TPF is co-chaired by the Indian Minister of Commerce & Industry and the U.S. Trade Representative. The 14th Ministerial-level meeting of the TPF was held in New Delhi in January 2024, with a focus on enhancing trade ties and addressing concerns related to bilateral trade.

GSP (Generalised Systems of Preferences) 

The GSP is a preferential trade program where developed countries offer reduced or zero tariffs to developing countries on a wide range of products. India gets the benefit of GSP which the USA offers for developing and under developed economies of the world, where tariff barriers are removed on selected items of imports. However, India does not currently benefit from the GSP provision. The US revoked India’s GSP status in 2019.

Defence and Security Dimension

  • Joint Naval Exercise (Malabar) - The Malabar exercise is a multilateral naval exercise primarily involving the navies of India, the United States, Japan, and Australia. It focuses on enhancing interoperability, fostering mutual understanding, and addressing shared maritime challenges in the Indo-Pacific region. The exercise, which began in 1992 as a bilateral drill between India and the US, has evolved into a key event for these four nations. 
  • Rim of the Pacific (RIMPAC) Exercise - It's a major multinational naval exercise hosted by the US Pacific Fleet in Hawaii. India's first official participation in the RIMPAC exercise (Rim of the Pacific Exercise) was in 2014. While India participated as an observer in previous editions (2006, 2010, and 2012), 2014 marked the first time an Indian warship, the INS Sahyadri, was part of the exercise. 

Military Exercise

  • Yudh Abhyas – joint military exercise being conducted annually since 2004 between the two nations. It is designed to promote cooperation between the two militaries while sharing training, cultural exchanges, and building joint operating skills. YUDH ABHYAS 2024 held at Mahajan Field Firing Range, Rajasthan.

The exercise focuses on enhancing U.S – Indian mutual cooperation by building on existing capabilities, aircrew tactics and force employment.
  • Red Flag Exercise – A US Air Force led Exercise conducted among the North American countries and Europe. India has also been made a partner to the Red Flag Air Force Joint Exercise. The Indian Air Force (IAF) first participated in the Red Flag exercise in 2008.
  • Obama visit in 2010 – USA offered the joint development of defence technology. It was first of its kind where USA for the first time was signing such an agreement with a developing country like India. President Obama called the relationship with India “one of the defining partnerships of the 21st century.”
  • The United States is the third largest defence equipment supplier to India, after Russia and France, 1st and 2nd respectively.
  • Security – There is a provision of an institution named US-India Homeland Security Dialogue which has to discuss the issue of terrorism and extremism and their counter strategy between the two nations. The Indo-US homeland security dialogue was launched in 2010 as the mechanism to a sequel to the signing of the India-US counter-terrorism initiative. First Homeland Security Dialogue was held in 2011.

Cultural Cooperation

There are millions of Indian origin people who live in the USA and the Indian diaspora has played a significant role in influencing the perception American Govt. towards India. Thousands of doctors, engineers and scientists working in NASA are of Indian origin.

Some eminent personalities in the US of the Indian origin include -

  • Satya Nadella: CEO of Microsoft.
  • Sundar Pichai: CEO of Alphabet (Google's parent company).

  • A mutual effort to combat tax evasion.
  • Under its provisions both the countries will exchange information to detect or discourage offshore tax evasion.

Key Irritants in India – US relationship

With all things going smoothly, there are some hurdles here and there, ne it anything. Similarly, some key irritants in India – US bilateral relations are as follows:

  1. Food Security Law of India – as per this law, the govt. will procure food grains in a huge quantity, which according to the USA is going to violate the de minimis subsidies of the WTO provisions. As per de minimis a developing state cannot offer subsidy more than 10% of the value of total produce. This issue was raised in the WTO meeting where India and USA were at loggerheads and final there was an agreement on developing a permanent ‘Peace Clause’ in the context of food subsidy. This was accepted by all the WTO members.
  2. USA Protectionist Policies – with the downfall of global economy from 2008, the Obama Govt. adopted a protectionist policy. The USA anti-outsourcing policy was announced in 2009 under which they immediately reduced the number of H1B Visas from 1.25 lakhs to 65,000 only. The same policy is being followed by Donald Trump. He has adopted “America First” Policy in which the US based companies are being directed to first offer jobs for the Americans.
  3. Global Climate Change Issue – the two nations differ in their global commitment to reduce CO2 emission. As USA wants India to also cut down the CO2 emission on the lines of the developed countries, India differs on this view and suggest more liability on the US and other developed countries in terms of cutting down CO2 emission.

India–US relationship in present times (2025)

The India–United States relationship in 2025 stands at a strategic high point, marked by growing cooperation across defence, trade, technology, and geopolitics. The partnership, rooted in shared democratic values, is evolving into a key pillar of the Indo-Pacific security architecture and global governance.

Key Areas of Cooperation:

  1. Strategic & Defence Ties - The two nations are deepening military cooperation through joint exercises (like Yudh Abhyas, Malabar) and defence technology sharing. The Initiative on Critical and Emerging Technologies (iCET) is a cornerstone of collaboration in AI, quantum computing, and space. India's role as a Major Defence Partner has led to co-development deals, including drone technology and jet engines.
  2. Economic & Trade Relations - Bilateral trade crossed $200 billion, with growing synergy in digital trade, pharmaceuticals, and clean energy. Efforts are underway to reduce trade barriers and promote supply chain resilience, especially in semiconductors and rare earths.
  3. Technology & Innovation - The U.S. and India are fostering deeper cooperation in semiconductors, telecom (5G/6G), and cybersecurity. Indian talent and tech firms remain vital to the U.S. innovation ecosystem.
  4. People-to-People Ties - Over 4.5 million Indian-Americans play a vital role in strengthening bilateral ties across academia, entrepreneurship, and policymaking. Student exchange and higher education linkages are robust, with the U.S. being a top destination for Indian students.
  5. Global & Regional Issues - Both countries align on maintaining a free, open, and inclusive Indo-Pacific, with counterbalancing strategies toward China. Collaboration extends to climate action, pandemic preparedness, and defending democratic norms globally.

Challenges

  • Trade disputes, visa concerns (especially H-1B), and differences on global political stances (e.g., Russia–Ukraine) remain areas of friction.
  • India’s strategic autonomy sometimes contrasts with U.S. expectations in multilateral alignments.

Conclusion

The India–US relationship is maturing into a comprehensive global partnership, driven by mutual interests and converging strategic goals. As the geopolitical landscape shifts, both nations are positioning their alliance as a key force for regional stability and technological leadership.
