India-US bilateral ties have had a remarkable trajectory, given that the two nations had a bitter ‘estranged’ relationship for almost four decades (since 1965), with sharp and seemingly intractable divergences in their strategic orientation and security interests. The US was deeply invested in military alliances during the Cold War decades to contain the former Soviet Union, while India preferred to remain non-aligned. Regional security compulsions saw New Delhi signing a friendship pact with the former USSR even while being a recipient of US development aid in many sectors, including food. But even with the USSR, though the military inventory relationship was very substantive, India adhered to its principle of not becoming part of any military alliance.
