This article analyses the evolving uses of social media during wartime through the IDF (Israel Defense Forces) Spokesperson Facebook and Twitter accounts. The conflict between Israel and Hamas-affiliated groups in November 2012 has generated interesting data about social media use by a sovereign power in wartime and the resultant networked discourse. Facebook data is examined for effective patterns of dissemination through both content analysis and discourse analysis. Twitter data is explored through connected concept analysis to map the construction of meaning in social media texts shared by the IDF. The systematic examination of this social media data allows the authors’ analysis to comment on the evolving modes, methods and expectations for state public diplomacy, propaganda and transparency during wartime.
