With smartphones, editing apps, and innovative approaches, some UN peacekeeping operations across the world are building a “digital army” aimed at combating mis- and disinformation on social media networks and beyond.
My concern is more the possibility of defining disinformation in some politically conveniemt manner.
Its already happening. In fact, looking at it from a wider perspective than nowadays teenagers are often able to, the modern "fight against disinformation" is just fighting propaganda with one's own propaganda. And if you read the Hittite and Egyptian descriptions of Battle of Khadesh, it isn't really a new thing either.
