Ironically, it actually did its job pre WWII.
Chamberlain realised he had fucked up. Britain didn’t have the forces to actually resist the Nazis. Appeasement was to buy them time to rearm. When the war actually started, Chamberlain fell on his proverbial sword, to give Churchill a clean slate and a functional military to work with.











Not recovering, almost certainly, dead is another matter. Modern medicine can do an insane job of keeping someone “alive” long past the point their body has given out. Particularly when money isn’t a factor.
My guess is that he’s either brain-dead, but kept “alive” by machines, or wishes he was brain-dead, while being kept in pain by machines.
