The spectator is allegedly a reliable media source, I am not personally familiar.
(I really don’t know, but it does seem that this info at least is coming from multiple places?)
It's a funny old magazine though, they really do get all sorts in there and print stuff that others wouldn't. It's entirely editorial though with huge biases.
I'm glad it exists and read it often, but I'd go checking everything I read in it if I was after some facts.
(by contrast, while the Daily Mail is absolutely terrible at opinion and domestic news, they seem to have some capacity left for doing overseas reporting that isn't just wire service, so if they report on overseas events you can be reasonably sure that something like that happened)
The question isn't whether to trust The Spectator, it's whether to trust this unconfirmed, unnamed source.
Gordon Chang has been making this prediction for almost a quarter century. Will it happen before or after the Mayan calendar predicts the end of the world??
