"Authoritarian political ideologies have a vested interest in promoting fear, a sense of the imminence of takeover by aliens and real diseases are useful material"

This quote by Susan Sontag suggests that authoritarian political ideologies frequently use worry as a tool to maintain power. By promoting fear of an imminent takeover by aliens or real diseases, authoritarian routines can create a sense of urgency and panic that can be utilized to manage the population. This worry can be used to validate overbearing policies and to dissuade people from challenging the status quo. By developing a sense of worry and insecurity, authoritarian routines can preserve their power and control over the population. Ultimately, this quote suggests that authoritarian regimes have a vested interest in promoting fear in order to maintain their power.
