"This paper examines online discourse about the White Helmets, a volunteer rescue group that operates in rebel (anti-regime) areas of Syria. The White Helmet’s humanitarian activities, their efforts to document the targeting of civilians through video evidence, and their non-sectarian nature (that disrupted regime-preferred narratives of rebels as Islamic terrorists) put the group at odds with the Syrian government and their allies, including Russia. Consequently, they became a target of a persistent effort to undermine them. Disinformation can be defined as information that is deliberately false or misleading. Its purpose is not always to convince, but to create doubt. Bittman (1985) describes one tactic of disinformation as “public relations … in reverse” meant to damage an adversary’s image and undermine their objectives. We argue that disinformation is best understood as a campaign—an assemblage of information actions—employed to mislead for a strategic, political purpose. Prior research and investigative reporting have characterized the campaign against the White Helmets as disinformation, due to its connection to Russia’s influence apparatus, its use of false and misleading narratives to delegitimize the group, and its function to create doubt about their evidence documenting atrocities perpetrated by the Syrian regime and their Russian allies. This research examines “both sides” of the White Helmets discourse—exploring how the White Helmets promote their work and foster solidarity with online audiences through their own social media activity and through episodic attention from mainstream media, and examining how the campaign against the White Helmets attempts to counter and delegitimize their work through strategic use of alternative and social media. We do not make any claims about the veracity of specific pieces of content or specific narratives shared by accounts on either side of this conversation. However, we do highlight how the campaign against the White Helmets reflects emerging understandings of disinformation in this context." (Page 2)
