Much has been written, and rightly so, about the potential that artificial intelligence (AI) can be used to create and promote misinformation.

And it is important for another reason as well: While nation-state interest in information is certainly not new, the incorporation of AI into the information ecosystem is set to accelerate as machine learning and related technologies experience continued advances. The present article explores the intersection of AI and information integrity in the specific context of geopolitics.
