Evolution

Relations moved from Cold War “estrangement” (India’s non-alignment, US-Pakistan ties) to engagement after 1991 and especially after the 2005 civil-nuclear deal — now a multi-dimensional partnership built on shared democratic values and converging strategic interests (notably on China).

Pillars of the partnership

  • Defence & strategic — “Major Defence Partner” status, the foundational agreements (LEMOA, COMCASA, BECA), the 2+2 ministerial dialogue, and joint exercises;
  • Trade & economy — the US is among India’s largest trade partners; growing investment;
  • Technology — the iCET (Critical & Emerging Technologies) initiative, semiconductors, space;
  • Indo-Pacific — the Quad and a free, open Indo-Pacific;
  • Diaspora — a large, influential Indian-American community.

Irritants

Frictions include trade and tariff disputes, visa (H-1B) issues, differences over Russia (India’s defence/energy ties, CAATSA sanctions risk), data and digital-trade rules, and occasional commentary on internal matters. These are managed within a broadly positive trajectory.

The way forward

The relationship is anchored by strategic convergence on the Indo-Pacific and China, deepening technology and defence co-production, and people-to-people ties — while India preserves its strategic autonomy and multi-aligned posture.

UPSC angle

Organise around pillars (defence/foundational agreements, trade, tech/iCET, Indo-Pacific/Quad, diaspora) and irritants (trade, H-1B, Russia/CAATSA). Note India’s strategic autonomy.
