I guess it's inevitable in a godless society. We create our own idols and are furious when we discover they are flawed, because it indicates that we ourselves are flawed, and the extent of our own self deception.
I'm looking forward to how this plays out in the press - it's summer, there won't be many political stories coming out, hopefully it will run for a while and then we'll get the Netflix documentary in 2026.
It's all way more interesting than the book itself.
As for what becomes of the book in the long term, who knows? Pps have pointed out there's a long history of fake/self-aggrandizing bestseller memoires - eg most Hollywood chronicles, Papillon, San Michele - but most aren't written as a way of covering up straight out theft, and have an element of entertaining the reader in and of themselves, rather than being just a long, dishonest personal whinge.
