The evolution of India–US relations in the last two decades has been remarkable, and the two countries are closer now than they have ever been. On the one hand, the rapid expansion of India's Western-influenced middle class has pushed the country to align with many American positions; on the other hand, the US too has recognised India's growing importance in a post-9/11 world. The principal driver of this relationship is a growing convergence of economic and strategic interests, with the existence of a large and successful Indian diaspora in the US acting as a further valuable bridge. American military aid to Pakistan remains an unsettling factor in this relationship, but both sides are learning to manage their differences without abandoning their core concerns or creating a crisis. Short of an unexpected shock to the system, India–US relations will continue to improve steadily in the future and become one of the most exciting partnerships in the 21st century.
