Subversion can generally be broken down into internal and external subversion, but this distinction is not meant to imply that each follows a specific set of unique and separate tools and practices. Each subversive campaign is different because of the social, political, economic, cultural, and historical differences that each country has. Subversive activities are employed based upon an evaluation of these factors. This breakdown merely clarifies who the actors are. While the subversive actors may be different, the soon to be subverted targets are the same. As Paul Blackstock identifies, the ruling and political elites are the ultimate targets of persuasion because they control the physical instruments of state power.
