Peacekeepers are seen as a UN tool for promoting domestic changes in host countries, but little is known about the political consequences when officers return home. During the last 10 years, Brazilian presidents appointed a significant number of former peacekeepers to key political functions. How and why do former peacekeepers end up so involved in government affairs? To answer this question, this paper focuses on the array of skills acquired by peacekeepers in domestic missions and reinforced abroad. Drawing on a set of semi-structured interviews and questionnaires to military, former political decision-makers, and researchers, as well as other primary and secondary sources, this paper details how political articulation, experience in conflict management, and prestige empowered Brazilian military officers to resume their tradition of intervention in politics. This paper also shows that peace operations can produce deleterious outcomes for troop-contributing countries in the Global South. [ABSTRACT FROM AUTHOR]
