Greer has written two speculative-fiction books about the downfall of the US: "Twilight's Last Gleaming" and "Retrotopia", apart from lots of other books.
I found both of the above two books entertaining as well as thought-provoking.
Why would the USAF be the last to know/admit the F35 has failed? It's been open knowledge for the rest of us for the last 10 years or so. I'm on record on the Webs for calling it today's 'Brewster Buffalo' Pilots' Graveyard for years.
JM Greer called it the 'lard bucket' in his book "Twilight's Last Gleaming", also years ago.
From what I've seen it mostly it's Americans writing about the US losing the next world war in fictional books like Ghost fleet: A Novel of the Next World War or Twilight's Last Gleaming.
