"Fascism" is in decline actually due to globalization and internet...
Hmmm... Tools (such as the Internet) are usually value-neutral. They can be used for both positive and negative ends. You can build a house with a hammer, but you can also kill someone with it. The Internet is not making fascism impossible or democracy necessary. It all depends on who controls this new means of communication. Ask the Chinese how it's done.
New communication media have been harnessed by totalitarian regimes before. See the Nazis' use of radio. For the first time, the leader could speak directly to the masses through a media totally controlled by the state, without going through the established printed media (newspapers). Hitler made much use of it.
In a similar fashion, Trump speaks directly to his audience through Twitter. He doesn't need established media anymore, because he can use new ones: tweets, and an army of websites, bloggers and the likes relaying his message. So he controls the narrative, at least the one his devoted followers receive.
