Sir — This refers to the editorial, “Deliverables matter” (January 26). Prime Minister Narendra Modi has not only changed the course of domestic politics but also re-invigorated India’s international relations. His personal rapport with the most powerful person of the world, US President Barack Obama, is visible to all. Mr Modi’s diplomacy has also succeeded in breaking a seven-year deadlock over the civil nuclear agreement. Additionally, the Defence Technology Transfer Initiative and America’s support for India’s role in Afghanistan and in the Asia-Pacific region, are also significant developments. Mr Modi has revolutionised India-US ties.
