Facts always create problems for authoritarian regimes.
So they do everything they can do get rid of facts.
The primary reason they spread disinformation is not to get people to believe the nonsense (which is merely an occasional bonus), it is to get people to give up on finding the truth. Once people have no substantial quantity or quality of truth, they can be entirely manipulated.
This regime is following the standard path to authoritarianism.
This regime is just following the same path openly.
Give Trump some gold points for not being a hypocrite like all of his predecessors.
