Former US National Security Advisor and Secretary of State Henry Kissinger, who died on Thursday at 100, embodied the term realpolitik, an outlook based on practical rather than moral or ideological considerations. Celebrated and reviled in equal measure, he was regarded as the architect behind US foreign policy in the 1970s. Kissinger played a role in the toxic relationship between the US and India during this time, as he and President Richard Nixon denigrated India and its leaders.
