All media in the US is controlled by just a few companies. Both companies and military units are working on forums to control the discussions. Sometimes pretending to be on both sides to make a discussion deviate from the actual issues.

Some US "friend"-states also have a huge influence in the online discussions, and in the media. They have their own military units and action groups.

And this is just the beginning of the manipulation that is going on online by actors.

The foreign influence is just minor and is exaggerated by the internal influencers as a distraction. That way the internal influencers can pretend that they are doing good work.

And this is just the beginning.

A good solution is to detect logical fallacies in the stories. How much are they used to push a certain idea? Is there actual evidence? And/or is there possible manipulation by an involved party.
