"Drawing on a host of different primary and secondary sources and more than 150 original interviews from across the U.S. government, the joint force, industry, civil society, and subject-matter experts from nine countries around the world, researchers examined how China, Russia, and North Korea have used disinformation on social media and what the United States and its allies and partners are doing in response. The authors found that disinformation campaigns on social media may be more nuanced than they are commonly portrayed. Still, much of the response to disinformation remains ad hoc and uncoordinated. Disinformation campaigns on social media will likely increase over the coming decade, but it remains unclear who has the competitive edge in this race; disinformation techniques and countermeasures are evolving at the same time."
