Again, this is conveniently only partially correct. There is a lot of obvious propaganda targeted at the uneducated/uninformed peoples but the real propaganda is everything that you just accept as truth. You would assume incorrectly that the US is bad at propaganda if you just equate propaganda with Fox news but it goes much deeper than that.
In the 1950s the CIA began the work to create a vast propaganda network in order to combat the spread of socialism. They staffed some journalists in all the major news spots (i.e. NY Times etc) and started all these convenient organizations around the world to help spread false information about their enemies.
One of the many many organizations they founded was Radio Free Asia which is very active to this day. They use anonymous sources for most of their propaganda pieces, or cite one of the other CIA funded organizations, and then all major western news medias parrot their articles/claims. The founder of the National Endowment for Democracy admitted that the NED is a CIA cutout and they regularly give “grants” to journalists to spread their propaganda.
On top of that they have had direct involvement in hollywood since forever in order to control state messaging. Targeted social media campaigns, especially on reddit. It was accidentally revealed that one of the most active cities on reddit just so happens to be a military base 😂 Unfortunately, these things are just the tip of the iceberg.
There is a lot that Americans have been brainwashed into accepting as truth and it is certainly amongst the educated as well. It may sound crazy or conspiratorial but it is unfortunately the truth. It is a bit shocking once you start pulling on that thread.
