Propaganda and fake news

In the Cold War, US invented the notion that propaganda by enemies of the US is...propaganda, while propaganda by US and its allies is the truth.  Something similar is happening these days with the stories of "fake news".  I like it when Obama speaks against "Fake News".  I mean, is there a source producing more fake news around the world than the US government?   And the US intelligence report on Russian hacking kept talking about Russian propaganda TV stations. What about US propaganda TV station in Arabic?
