Re: British reactions to the War of Bangladeshi Liberation. It's worth noting that Edward Heath was the only NATO Leader to be given the Bangladesh Liberation War Honour for foreign civilian leaders which was otherwise awarded to Indian, Bhutanese, Nepali and various communist leaders who had supported the Bangladeshi independence effort.
Two of my best friends had family in Bangladesh at the time, they both lost grandparents in the genocide, and as I spent yesterday with both of them, I showed them this article and we talked a bit about the effect of that national trauma and how it's still felt really strongly today.
