india is pretty much on the grip of hindu fascism, and the central tenet of it is to combat the muslim minority of india. we are talking state sanctioned lynchings here. it is more likely, imo, that foreign policy took precedence and it is insulated from domestic policy. india has ties with all the gulf countries and it is currently playing nice with iran and the central asian countries as part of their policies of building bridges towards russia. and voting against this motion probably wouldn't score them any points at home anyways.
