he can't shut down congress.
I'm sure he will try if they suddenly decide to develop a spine (for example, if Democrats gain power, or – *gasp!* – the Republicans actually come to their senses, and attempt to impeach him). I expect that the day that happens will be essentially the end of the United States as we know it, and we will become a collection of mostly independent nation-states instead of US states. Ordinary life on the ground probably won't change too noticeably, but the economy will be effectively destroyed and broken into at least 50 separate pieces.
No, there's no authoritarianism going on. None at all. Everything is perfectly normal.
Welcome to
The Twilight Zone....
As for shortwave, as much as I like the concept of using it as an international broadcast medium, it does seem like it's basically dead for that purpose.
Plus with the cost of energy nowadays, running a 500+ kW transmitter for even a few hours every now and then is incredibly expensive and unlikely to be sustainable for long (how is WRMI doing? Last I knew, I *think* they actually were doing OK relative to many of the other US-based SW stations, not that that is saying much).
VOA on SW, therefore, probably is well past its prime, and should've been shut down years ago. However, regardless of whether or not anyone listens or how significant or relevant it is, VOA's SW signals are an example of soft power that shouldn't be messed with carelessly.
FM stations are OK in places that can receive such signals, but there are deeply rural places where most FMs can't fully reach, plus if a government turns against the US and decides to pull VOA programming off domestic radio, blocks the Internet, and so on, something like SW might be the only option, however few listeners there still may be or how few receivers still exist.
The shortwave transmitters collectively consume tens of Megawatts of power. Why pay that electric bill just for music fill? I still think they will be shut off as soon as someone realizes this.
You're probably right.
