Famously debunked the justifications for the Iraq war at the time they were being spread.

The Russians view Fox News as a balanced news source.
Walter Kronkite, perhaps the most famous TV anchor in US history was publicly against the Vietnam war https://en.m.wikipedia.org/wiki/Walter_Cronkite
Iraq war is where "embed" journalism became the only acceptable source where journalists were killed by US.
Fox News is the most widely watched news network in the US.
Tucker Carlson has the highest rated show on that network and has taken an anti-Ukraine stance.
Russia has banned foreign media, in addition to restricting local media to publishing the government view.
Since I'm British, and you'd probably consider the US and UK equivalent for this purpose, here's a major British newspaper article arguing against NATO action in Libya: https://www.theguardian.com/commentisfree/2011/mar/23/nothin...
(Given https://en.wikipedia.org/wiki/Guardian_US, it probably counts for the US anyway.)
Yes the US has problems. But Russia is just on another level considering that being a free and independent media source is literally illegal there.
Even forgetting the Pentagon Papers already mentioned, papers have published the abuses in Guantanamo and the Iraq War Logs. Plenty of articles have documented killings of civilians by US drones. And plenty of editorial boards have written articles calling on the US to end whatever current war it's fighting.
Sure, big media probably kowtows more to the government than we'd like, but they absolutely are free criticize the wartime actions of the government.
