Question: Who is the Prime Minister of the United Kingdom whose book a thesis by John F Kennedy alludes to?
Sentence (from "Why England Slept"): Published in 1940, the book examines the failures of the British government to take steps to prevent World War II and is notable for its uncommon stance of not castigating the appeasement policy of the British government at the time, instead suggesting that an earlier confrontation between the United Kingdom and Nazi Germany could well have been more disastrous in the long run.
Relevant evidence: No
