The funny thing is, India always wanted to be an equal partner/ally of the US, since its independence, but was continuously rebuffed. Every move of India was an effort to get close with the West. India owes a bit to FDR and Truman for applying pressure on the UK to decolonize, and the American public for being staunch supporters of Indian independence. The Green Revolution in India, crucial for creating Indian food security, was spearheaded by a US govt programme and Norman Borlaugh. The IITs were created through largely Western funding and collaboration (with the exception of IIT Bombay, which was created with Soviet funding). India (under Nehru) helped convince most of the West Indies and Africa to join the UK Commonwealth, in spite of their own torrid histories of being colonized.

But then USA decides to do stuff like supporting a belligerent China (which had the infamy of invading every one of its neighbors), supporting Pakistan openly (which was an easier puppet because of the military rule, unlike India), assassinating people in the Indian nuclear programme (allegedly), silently supporting the Bangladeshi genocide. And in spite of all this, India didn't choose to go to the Soviet sphere of influence, but tried to create one based on mutual partnership, a sphere that remains the largest today (the Non-Aligned Movement).

All in all, the USA and India share a lot of common goals and objectives, but the US must realize that India wants to be a strongly independent partner, like say France, and not a puppet partner like the UK or Germany.
