Widespread disinformation, use of social and state media, news agency hacking, fake news broadcasts, constant pressure on international organisations… all the modern means of communications are being put to use to influence public opinion and governments. Saudi Arabia, the United Arab Emirates, and their allies are attempting to subjugate the state of Qatar through these means and by deploying an economic blockade.

François Chauvancy, a general who has contributed to the research of Nato's working groups into strategies of influence and information operations (2005-2014), shares his analysis of this war of influence in this book.
