The will to influence the cognitive domain of humans has always been a part of war. The technological development within communication and information has expanded the means and ways to do so. This thesis explores how the use of narrative in strategic communication can function as a weapon in the perspective of cognitive warfare. Using narrative analysis, key elements of Israels narrative on the war in Gaza is identified on platform X. The components are then analyzed from a cognitive perspective to find which elements can affect human cognition. The findings show that the narratives contain elements capable of shaping how reality is understood. The research contributes to the theoretical discussion on how communication can act as tool to influence human cognition that can be applicable to other conflicts. It offers insights on how cognitive elements can be used as a part of military strategy to legitimize violence.
