Mainstream media reported about the horrors of Vietnam. Independent journalist were allowed to document these atrocities. Neither of these things happen anymore.

The US government made very sure to never repeat the mistakes of Vietnam. They use propaganda regularly to brainwash people into thinking our armed forces are the good guys. Journalist are now embedded into our fighting forces and they are tightly controlled

There is no independence in main stream media anymore. It was always bad, but now it is ridiculous. All major media leans either heavily conservative or somewhat conservative. There is no real progressive media, at least not anything that could influence the masses.

The wealthy have definitely won this battle.
