Private Military Companies (PMCs) and Peacekeeping

In the late 1990s, a new private military company (PMC) from South Africa, Executive Outcomes, intervened in Angola and Sierra Leone, where the company's operations ushered in a ceasefire. Still, when Executive Outcome's CEO, Eeben Barlow, declared his PMC capable of doing "what blue helmets could not," few in the peacekeeping and NGO world took him seriously. Twenty years later, after the rise of the Russian PMC Wagner Group, peacekeeping and mercenaries are direct competitors. Countries who traditionally contributed soldiers to the UN, such as Rwanda, Uganda, and Burundi, now market their troops to Exxon and the Gaza Board of Peace. Whether UN peacekeeping can survive this latest round in the privatization of warfare remains to be seen.
