A certain US ex-President gave a talk on the subject only a week or two back. This is what he had to say:
“You just have to flood a country’s public square with enough raw sewage. You just have to raise enough questions, spread enough dirt, plant enough conspiracy theorizing that citizens no longer know what to believe.
Once they lose trust in their leaders, in mainstream media, in political institutions, in each other, in the possibility of truth, the game’s won.”
Now he was referring to others so there is no chance at all it applies to him or the playbook of his presidency.
