This chapter offers an insight into the complex relationship between peace-making, peace agreements and peacekeeping. It considers their interactions at the strategic, operational and normative levels. First, the chapter reviews the connections between peace-making, peace agreements and peacekeeping. It demonstrates that modern peacekeeping operations, typically deployed into contexts where there is little or no peace to keep, have an increasingly important role to play in the peace-making process. Second, the chapter assesses the normative issues that most impact on peace-making, peace agreements and peacekeeping. It discusses how the strategic peace versus justice debate manifests at the operational and tactical levels, and is amplified by the increasing trend of operations mandated with protection of civilians, human rights and international criminal justice tasks. It explores how this mandate trend can complicate an operation’s role in the peace-making process due to tensions between its multiple responsibilities.
