I could do that!
If you'd like to be, say, an "Infrastructure Rehabilitation Coordinator" in the Democratic Republic of Congo, or a "Child Survival Manager" in Mozambique and there are such jobs because Food for the Hungry International is recruiting for these very positions, it could help to have a Master of Arts in Diplomacy. Mightn't harm, anyway. Norwich University is offering the qualification and, interestingly, you can do it online. The course has lots of stimulating seminar topics: "Conflict Avoidance, Prevention, and Containment in the International System" and, if that doesn't work, there's "Military Intervention and Conflict Management in the International System". In others words, peace and peacekeeping.
