What does that have to do with my comment?
Fighting Germany ended in disaster for the UK and the British Empire, much more was lost than was gained, and it's not a comeback to state "APPEASEMENT" as if that policy was self-evidently wrong.
Appeasement is certainly an appropriate comeback.
The choices in September 1939 were fight Germany or appease Germany.
Was there some third option? An option that eight decades of rigorous history studies have yet to reveal?
did any evidence ever materialize to prove that Germany’s ambitions were ever going to be self-restrained?
Sudentenland, Czechoslovakia, and Poland, those would all suggest Nazi Germany had no intention of stopping for a long time.
