False flag
False flag is a term used by conspiracy theorists to suggest that various world events and crises, such as terrorist attacks and mass shootings, were actually orchestrated by governments or sinister forces in furtherance of a political or social goal, such as gun control or sowing public fear. Historically, the term has been used to refer to a military or political operation carried out with the intention of blaming an opponent for it, often as a pretext for going to war.
