Using culture to bring about change to a political system through integration of political warfare and political action and the targeting of cultural vehicles and institutions is another tool of subversion. The use of the arts or more broadly culture is primarily a tool for external subversives, as internal subversives are generally citizens of the country and share the same culture. It is a tool that takes a longer period of time to implement and its effects are revealed over time, as opposed to those of a terrorist attack or civil unrest. Therefore, one could classify this tool as an element of strategic subversion. The targets of cultural subversive activities are traditionally film, literature, popular music, educational institutions, mass media, religious organizations, charitable organizations and other forms of art. The intended results of these activities are to persuade or co-opt publics, discredit the ideas of enemies and splitting factions within the enemy's camp.
