Have you been on the Internet as an adult ever? Have you been on X? What about Facebook? America is "one mouthpiece"? This is one of the most puzzling takes I've ever seen.
Americans literally post 10K articles a day about how bad the administration is and all the bad that will result from going to Venezuela ... and multiply that for literally every other thing the govt does. There isn't one thing that happens that doesn't have hundreds of posts online and in papers explaining why America is so evil for doing it.
You have no idea what you are talking about. Have you sampled the media landscape in Tehran or Beijing? I have sampled both ... FROM those locations. Its night and day.
Even the media landscape in your typical Western Alliance country (Singapore, Japan, South Korea, UK ... etc.) cannot come close to what you see in America.
