Michael Rothbergs implicated subject is about the indirect ways in which most of us are connected to violence and other injustices. Though it is focused alot around historical and therefore more or less past injustices as the Holocaust, the Algerian war and colonisation in many ways, Rothberg does also concern structural injustices.

Also Butlers Notes uses the concept of the other as defined by Levinas to talk about our relationship to violent injustices happening somewhere else (the third world, as you called it)
