"The oppressed were organized in Liberation Movements which started guerilla warfare against their oppressors. Though poorly equipped, their determination and commitment led to unexpected success. To combat the national liberation movements, the imperialists could no longer come out in the open and expose themselves. This would make them lose face. All they wanted was to "invisibly" control these countries. It is in this context that the modem mercenary has become an important tool of imperialism. Mercenarism as a form of soldiering is used as a vehicle for fighting the liberation movements and independent developing countries."
