Prime Minister Narendra Modi’s meeting with President Joe Biden at his home in Greenville, Delaware, was in the nature of a farewell exchange as they both celebrated the growing strength of India-US ties. The US approved a pending deal for the sale of 31 sophisticated drones that operate below the radar and at high altitudes. A decade ago, the US would not have sold this kind of defence equipment to India, but now, with expanding strategic cooperation, buying defence equipment from the US is routine.
