Abstract
This chapter analyses the dynamics of humanitarian intervention and peace operations. It begins with a discussion of the changing nature of peacekeeping since the cold war and how peacekeeping expanded in the post-cold war period, creating demand, opportunities, and incentives for intervention that resulted in an unprecedented increase in the number and scale of military interventions by United Nations forces. Today, humanitarian interventions are larger, more complex affairs. The chapter goes on to examine how post-cold war operations shaped peacekeeping debates; peacekeeping since 2000; the benefits and challenges of the regionalization of peacekeeping; and evolving norms in contemporary peacekeeping. It also considers the politics of humanitarian intervention, especially at the UN Security Council, and how public opinion of humanitarian intervention is shaped by media coverage and casualties. Finally, it describes the military character of peace operations as well as problems and prospects surrounding humanitarian intervention and peace operations.
