Although volunteer agencies’ rhetoric emphasized international friendship, in reality volunteers often faced a wealth of conflicts in their daily lives. This chapter explores conflict at both interpersonal and international levels. Many volunteers faced suspicion and enmity in communities suffering the legacies of European colonialism and confronting American neoimperialism. Some host communities regarded volunteers as spies or government agents; others merely resented inexperienced foreigners claiming to hold the key to their development or who professed egalitarian ideals whilst living in relative luxury. In numerous cases, volunteers became entangled in broader conflicts between nations, blocs and ideologies, and in the divisions between East and West, First World and Third World. As a result, the day-to-day experience of numerous development volunteers was marked by tense encounters ranging from minor slights to violent conflict.
