Psychological warfare refers to the use of psychological tactics to influence and manipulate the thoughts, emotions, and behaviors of individuals or groups. It often aims to create fear, confusion, or distrust among opponents, thereby weakening their resolve without direct physical confrontation. This strategy can be employed in various contexts, including military operations, political campaigns, and social movements. Techniques of psychological warfare may include propaganda, misinformation, and intimidation. By targeting the psyche of the enemy or the public, practitioners seek to gain an advantage. Historical examples include the use of propaganda during World War II and Cold War tactics to undermine rival nations.
