If the war had a noble purpose, it was this - to end the inhumanity those photographs showed. While India rarely spoke about its imperative as the moral one, and few people steeped in realpolitik can shed their cynicism when a politician speaks in moral terms, and the intervention certainly suited India's strategic interests, the fact remains that in the annals of humanitarian interventions, few were as swift, successful, purpose-driven and with humanitarian goals as the Indian intervention to liberate Bangladesh. India went in when it was attacked, and left before its troops became unpopular.
