This chapter documents the responses to peacekeeping misconduct and how such abuse/violations have been handled by the UN and troop-contributing countries (TCCs), what is lacking, and how a culture of accountability and justice can be established to deter and where necessary prosecute criminal behavior. There is a review of the overall number of SEA occurrences and how the difficulties of enforcing criminal accountability have created a culture of impunity and immunity for UN peacekeepers. Selected cases are used to substantiate the claim that the UN’s zero tolerance for SEA, since the 2005 Zeid report, has in practice done little to change the TCCs’ zero action. The 2015 UN Report of the External Independent Review Panel is discussed along with other pressing concerns and reform suggestions.
