Offensive terror can be defined as the killing of people, destruction of property, kidnapping, etc. It is usually a minor part of subversion and, "is used not to exert force in the transfer of state power, but is meant to cower the people or ruler". Force used in this manner is meant to reinforce other forms or persuasion in addition to cowering the people or leaders. Additionally, much like civil unrest and agitation, it raises the question of whether or not the state can provide security for the population. Terror also provides a practical motivation of physically removing political opponents. The assassination of an organization's leader may open the door to a successor that is more friendly to the subversives position or possibly someone that has successfully infiltrated the organization and is in fact one of the subversives. Bribery is one of the most common tools of subversion. Most societies see bribery as a form of corruption and it used as a subversive tool because it, "implies the undermining of existing rules of political or moral conduct". It can also be one of the less reliable tools as well. Bribed officials are only useful if they take action. However actions taken over a period of time draw suspicion from the public. The official must be able to carefully conceal their actions or perform only key functions and action. For these reasons bribed officials are most effective when they are asked to take immediate action. In the case of external subversion, bribery is usually used for influence rather than for actions. Recent writers, in the post-modern and post-structuralist traditions (including, particularly, feminist writers) have prescribed a very broad form of subversion. It is not, directly, the parliamentary government which should be subverted in their view, but the dominant cultural forces, such as patriarchy, individualism, and scientism. This broadening of the target of subversion owes much to the ideas of Antonio Gramsci, who stressed that communist revolution required the erosion of the particular form of 'cultural hegemony' within society. Theodor Adorno argued that the culture industry and its shallow entertainment was a system by which society was controlled through a top-down creation of standardized culture that intensified the commodification of artistic expression; in 1938 he said that capitalism has colonized every aspect of life so much that "every pleasure which emancipates itself from the exchange-value takes on subversive features". 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.
