On 16 June 2026, the Pentagon retired a name it had carried for eight years. U.S. Indo-Pacific Command reverted to its older title, U.S. Pacific Command, and Defense Secretary Pete Hegseth marked the occasion tersely on social media: “U.S. Pacific Command is back.” The ‘Indo’ in Indo-Pacific had been, more than anything, an American acknowledgement of India’s centrality to its Asia strategy. Dropping it raises a question New Delhi cannot afford to dismiss: can the Indo-Pacific remain strategically coherent if India is no longer central to it, and does the shift point to something deeper than a bureaucratic housekeeping exercise?

The Making of the Indo-Pacific

The Indo-Pacific was an Indian idea before it became an American strategy. The concept’s modern geopolitical usage is widely attributed to Indian naval strategist Gurpreet Khurana, whose 2007 paper described the arc linking Indian Ocean energy routes to East Asian manufacturing centres as a distinct strategic theatre.[1] Japan’s Prime Minister Shinzo Abe gave it political momentum in his address to the Indian Parliament the same year, describing the Indian and Pacific Oceans as a “Confluence of the Two Seas”.[2]

The first Trump administration elevated this from geography to doctrine. The 2017 National Security Strategy defined the region as stretching “from the west coast of India to the western shores of the United States” and placed it at the top of US regional priorities.[3] In May 2018, Defense Secretary Jim Mattis renamed Pacific Command to Indo-Pacific Command. The Department of Defense announcement stated the change reflected “the increasing connectivity between the Indian and Pacific oceans”.[4] The name was not neutral cartography. It was a signal that the United States considered the Indian Ocean as relevant to the China competition as the Western Pacific.

Why India Became Central

India mattered to this construct because of its landmass and position. It anchored the western end of the map, commanded sea lanes through which a large share of global energy and trade passes, and offered the only large democratic power in Asia capable of independently complicating Chinese ambitions over the long term. The Biden administration’s 2022 Indo-Pacific Strategy made the investment explicit: it pledged to “support India’s continued rise and regional leadership”. It named it first among the leading regional partners Washington would cultivate beyond its five treaty alliances (Japan, South Korea, Australia, the Philippines and Thailand). The strategy defined the region as stretching “from our Pacific coastline to the Indian Ocean”, pushing the western boundary further than the 2017 document.[5]

The Quad became the flagship expression of this alignment. At the Wilmington Summit of September 2024, the four leaders declared themselves “more strategically aligned than ever before”, representing “nearly two billion people and over one-third of global GDP”.[6] Yet the partnership always rested on a concealed tension. Washington wanted India to be part of a deterrence architecture aimed at China; New Delhi wanted technological and........
