I haven't read it but the summary here seems useful: https://www.amazon.com/Blood-Telegram-Kissinger-Forgotten-Ge...

> Giving an astonishing inside view of how the White House really works in a crisis, The Blood Telegram is an unprecedented chronicle of a pivotal but little-known chapter of the Cold War. Gary J. Bass shows how Nixon and Kissinger supported Pakistan’s military dictatorship as it brutally quashed the results of a historic free election. The Pakistani army launched a crackdown on what was then East Pakistan (today an independent Bangladesh), killing hundreds of thousands of people and sending ten million refugees fleeing to India—one of the worst humanitarian crises of the twentieth century.

> Nixon and Kissinger, unswayed by detailed warnings of genocide from American diplomats witnessing the bloodshed, stood behind Pakistan’s military rulers. Driven not just by Cold War realpolitik but by a bitter personal dislike of India and its leader Indira Gandhi, Nixon and Kissinger actively helped the Pakistani government even as it careened toward a devastating war against India. They silenced American officials who dared to speak up, secretly encouraged China to mass troops on the Indian border, and illegally supplied weapons to the Pakistani military—an overlooked scandal that presages Watergate.

I am not sure that shows a level of obvious departure from realpolitik that the person claimed.

> Driven not just by Cold War realpolitik

The quote even says realpolitik was a major influence.

Right after the part you quoted it says he was also driven by a “bitter personal dislike.”
