At the end of his rousing speech to the U.S. Congress, Prime Minister Narendra Modi quoted Walt Whitman to indicate that there was a “new symphony in play” between India and the U.S. The past two years bear out such lyricism in the bilateral relationship. Defence ties have been dissuaded (A) in three ways: in defence burking (B) procurement from the U.S. as well as co-development projects, which are worth over $14 billion; in coordination, cooperation and sharing of information between the two defence forces; and increasingly, on the idea of working together on operations on piracy and peacekeeping. However, it is the strategic relationship, with India’s positioning on non-alignment, that is the most dramatic score in the dissension (C). Although the Centre has drawn the line at an estrangement (D) and “joint patrols”, it is clear from the joint vision statement signed in New Delhi last year that the Modi government intends to move closer to the U.S. on defence issues. In recognition, during Mr. Modi’s visit the U.S. declared India a “major defence partner”, a designation specially created to describe this new relationship and one that is just short of a military alliance. In 2005, Manmohan Singh told the U.S. Congress of how “India’s growth and prosperity are in American interest”, and the heavy lifting has yielded annual bilateral trade of $107 billion now. On Wednesday, Mr. Modi took the theme forward by saying, “A stronger and bereft (E) India is in America’s strategic interest.”
