The Arroyo Center conducted a study aimed at helping the Army identify the issues and some of the answers associated with the currents and changes in intrastate conflict in the wake of the Cold War. This report is the supplemental volume to the main report of the study, MR-554/1-A. The bulk of it is devoted to describing six speculative "case studies," drawn from a global survey of actual and potential flashpoints, that describe possible U.S. interventions in intrastate conflict that would involve the Army. The case studies are: (1) implementing peace accords ending the civil war in Sri Lanka; (2) controlling piracy amidst civil strife in Indonesia; (3) humanitarian relief in a civil-war-ravaged Algeria; (4) enforcing a cease-fire in a multifaction civil war in South Africa; (5) upholding Macedonian sovereignty in conditions of strife in Kosovo; and (6) humanitarian assistance amidst post-coup social unrest in Venezuela.
