The India-US relationship is entering a consequential and uncertain phase. The old vocabulary of a steadily deepening “strategic partnership” no longer adequately captures its trajectory. The relationship, while strong in defence and technology, is increasingly contentious in trade. Strategic impasse is defined by America seeking closer strategic alignment in Indo-Pacific against India’s insistence on strategic autonomy.
The central paradox is that whilst operational convergence between India and the United States is at a relatively fast pace, strategic convergence is clearly lacking. Defence cooperation, technology partnerships, and supply-chain integration are acquiring institutional depth, while the larger political relationship has become transactional, leadership dependent, and vulnerable to shocks.
For much of the period from 2005 to 2021, the relationship rested on a broad political narrative: democratic convergence, the Indo-Pacific, the Quad, technology cooperation, and shared concern over China’s rise and growing footprint. Under the Trump 2.0 administration, architecture has changed and in some respects been displaced by a deal-making approach centred on tariffs, trade balances, and investment commitments.
The difference matters. Strategic partnerships can absorb disagreements because they are underpinned by a larger conception of shared interests. Transactional partnerships tend to measure relationships thru reciprocity and gains. Making them even more volatile.
Trade has become the principal fault line
The most immediate source of instability is economic. Tariffs reached 50 percent in August 2025, linked explicitly to India’s purchases of Russian oil. An interim arrangement in February 2026 reduced the reciprocal rate to 18 per cent in return for substantial US purchases and commitments relating to Russian crude. Despite these steps, the Bilateral Trade Agreement remains unresolved.
This creates a contradiction. Both countries have powerful incentives for economic engagement, but their domestic political economies constrain the compromises required to achieve it. Washington wants greater market access and reciprocity; New Delhi cannot compromise politically sensitive agricultural interests. The result is recurring negotiation without a clean settlement.
For India, it is important not to disengage from the US market but to reduce vulnerability to American policy volatility. Diversification towards Europe, the Gulf, ASEAN, and other partners is therefore not an anti-American strategy. It is insurance against excessive dependence on any single economic relationship.
Defence cooperation as the Balancer
If trade is the principal source of instability, defence and technology cooperation remain the bastards of the relationship. The October 2025 ten-year Major Defence Partnership, successor initiatives to the iCET framework, the critical-minerals agreement, and continuing military exercises demonstrate defence cooperation moving beyond arms purchases towards interoperability, logistics, maintenance, and supply-chain integration. The American objective is to develop India as a regional logistics, maintenance, and technology hub rather than simply a recipient of American platforms.
This is perhaps the most important long-term opportunity.
For India defence relationship is not in terms of the number of platforms or systems. The real strategic gain is access to technology, co-production, intellectual property, advanced manufacturing, and resilient supply chains. If cooperation produces indigenous capacity, it strengthens India regardless of the future direction of US policy. If it merely produces import dependence, India would acquire the costs of alignment without acquiring corresponding strategic autonomy.
This distinction between buying capability and building capability will be the future driver of defence cooperation.
China remains the strategic glue—but with a qualification
The deepest structural reason for India-US convergence was and remains China. Both countries have an interest in preventing Chinese dominance of the Indo-Pacific, protecting critical technologies, and maintaining a favourable balance of power in Asia. India’s own experience of Chinese military pressure makes this imperative even more immediate.
Yet there is a growing disconnect between operational cooperation and strategic signalling. The relative silence on India and the Quad in the 2026 US National Defence Strategy, renaming the Indo-Pacific to merely Pacific, has unsettled expectations about the future Indo-Pacific architecture. At the same time, India continues to face Chinese pressure in areas such as rare earths and pharmaceuticals, partly as a consequence of its positioning within emerging China-countering supply chains.
This raises a critical question for New Delhi: how much strategic risk should India accept in the expectation that the United States will ultimately reciprocate?
India cannot afford an answer based merely on assumptions about American intentions. Washington’s China strategy will inevitably be shaped by its own interests, domestic politics, and global priorities. India therefore needs a relationship with the US that enhances its ability to manage China without making India dependent upon American strategic choices.
Strategic autonomy is not the opposite of partnership
The Russia question brings this tension into sharp relief. India’s long-standing defence relationship with Russia, including major systems such as the S-400, remains difficult to reconcile with Washington’s expectation of closer alignment. The CAATSA question continues to hang over the relationship. Yet neither side has an interest in forcing a decisive confrontation: Washington needs India within the Indo-Pacific balance, while India will not accept one-sided dependency-based alignment.
The likely outcome is therefore continued ambiguity.
For India, strategic autonomy is most useful, as it creates choices, not a mere slogan. A country that retains the capacity to say “no” has greater leverage when it decides to say “yes.”
India’s objective consequently is not to choose between alignment with Washington and multipolarity. It is to maximise optionality in the construct of India’s increase of its own relative power.
India’s growing weight will change the relationship
The most important factor in the medium term may not be American policy at all, but India’s own rise. The assessments project India moving towards becoming the world’s third-largest economy around the end of this decade, with GDP potentially reaching the $9–10 trillion range by 2035-40. A larger economy, expanding workforce, growing manufacturing capacity, and greater technological capabilities will alter the bargaining relationship with Washington.
The relationship could therefore gradually move from one in which India seeks greater American engagement to one in which both sides need each other.
This transition should influence Indian policy. Over the next five to seven years, India should prioritise building redundancy and extracting better terms rather than prematurely locking itself into any single strategic architecture.
That means simultaneously deepening the US relationship and expanding alternatives. India should seek binding outcomes from the defence and technology relationship: co-production of advanced systems, technology transfer, semiconductor capability, AI infrastructure, critical-mineral processing, and high-end manufacturing. At the same time, it should accelerate partnerships with Europe, the Gulf, ASEAN, Japan, South Korea, and other major powers.
This is not hedging against America. It is hedging against uncertainty.
The most likely future: durable but uneven
By 2035, the most plausible outcome is neither an alliance nor a rupture. It is a durable but uneven partnership. Defence and technology cooperation will probably continue to deepen, while trade disputes periodically resurface. India will use its growing economic weight to negotiate harder rather than automatically align more closely with Washington. The relationship will remain strategically important but will become less asymmetric.
A deeper convergence remains possible if the US institutionalises its Indo-Pacific commitment, delivers meaningful technology cooperation and develops a durable trade architecture. Conversely, repeated tariff shocks, sanctions over Russian defence purchases or an American retreat from the Indo-Pacific could accelerate India’s multipolar diversification.
The greatest danger is therefore not disagreement. It is unmanaged asymmetry.
India’s strategic risk therefore lies in accumulating increasing defence, technology and trade dependence on the United States without securing corresponding and durable American commitments in return. In such a situation, India could bear the costs of alignment while retaining no guarantee of strategic support.
The way forward
India should pursue five broad principles.
First, institutionalise the relationship. Personal chemistry between leaders can accelerate cooperation but cannot substitute for durable bureaucratic and legislative arrangements.
Second, compartmentalise disagreements. Trade disputes should not derail defence and technology cooperation, just as defence cooperation should not become a bargaining chip in every commercial negotiation.
Third, prioritise capability creation over equipment acquisition. Co-production, technology transfer and domestic industrial capacity are more valuable than additional imports.
Fourth, diversify deliberately. Stronger European, Gulf and Asian partnerships should give India greater resilience without weakening its US relationship.
Finally, retain strategic autonomy as a source of leverage. Autonomy should not mean equidistance from all powers. It should mean the ability to choose among partnerships according to Indian interests.
The India-US relationship is not at a crossroads between partnership and estrangement. It is undergoing a structural transition—from a largely convergence-driven relationship towards a more transactional and negotiated equilibrium.
India should neither romanticise the partnership nor undervalue it. The United States remains important to India’s technological, economic and strategic transformation; equally, India’s growing weight makes it increasingly indispensable to the United States’ Indo-Pacific strategy.
The objective for New Delhi should be clear: deepen cooperation where interests genuinely converge, diversify where dependence creates vulnerability, and ensure that every increment of strategic cooperation produces a corresponding gain in Indian capability or strategic choice.
The test is whether convergence can survive volatility without sacrificing India’s room for manoeuvre.
That is the pathway to a partnership that is durable not because it is frictionless, but because both countries increasingly recognise that their interests are better served by managing differences than by allowing them to define the relationship.
