The relationship between the world’s largest democracy (India) and oldest democracy (United States) has transformed dramatically from Cold War estrangement to a robust strategic partnership. 

Historic Evolution of India-US Relations 

• The Cold War Era and Estrangement (1947–1990):
  • Policy of Non-Alignment: Following independence, India adopted non-alignment to preserve strategic autonomy, creating geopolitical distance with Washington.
  • Key Points of Friction:
    • 1971 India-Pakistan War: India signed the Indo-Soviet Treaty of Friendship; US deployed the USS Enterprise task force in the Bay of Bengal in support of Pakistan.
    • Nuclear Tensions: India’s 1974 “Smiling Buddha” test triggered US export controls. The 1998 Pokhran-II tests led to immediate economic sanctions. 
• The Thaw and Turning Point (1991–2024):
  • Economic Opening (1991): The end of the Cold War and India’s 1991 economic reforms opened markets and initiated a thaw in relations.
  • Diplomatic Shifts (1999–2001): During the 1999 Kargil conflict, the US pressured Pakistan to withdraw forces. By 2001, remaining nuclear sanctions were lifted.
  • The Breakthrough (2008): The India-US Civil Nuclear Agreement ended India’s nuclear isolation and built foundational trust between the two democracies.
  • India designated as Major Defense Partner (2016): Foundational Defense Agreements such as LEMOA (logistics), COMCASA (communications), BECA (geospatial), etc. were signed.
  • The Indo-Pacific Focus (2017): Mutual concerns over China led to the revival of the Quadrilateral Security Dialogue (Quad) with Japan and Australia.
