Prime Minister Narendra Modi’s first state visit to the US was all that it was slated to be and went beyond the pomp and pageantry and the flattery to deliver what New Delhi had long sought from successive American presidents. For India, the transfer of critical American technology is at the heart of what President Joe Biden dubbed as the most defining relationship of the 21st century. It has the potential for India to leapfrog into the big league. Biden’s decision to share US state-of-the-art technology with a partner that is not a close military ally of the US could, in time, prove to be a game changer in the power politics of international diplomacy. Yet details of the agreements are not known and the devil may be in the detail.
