This story may both be true and be propaganda. What better kind of propaganda than stuff that is actually true?
What's important with propaganda is not how true it is, but the timing and the context and the reason why it is being deployed.
By pointing out that this is part of a campaign, I'm not saying I disagree with the motive for the campaign or the truth claims in the stories (or that I oppose them).
In my view, the mechanisms of propaganda are more interesting than the tit for tat between two morally mediocre powers.
But we don't get articles about the actual issues. We get this sort of breathless, fact-free nonsense about millions of people disappearing into "extrajudicial camps." It has no relation to reality and exists only to push a narrative and get clicks.
