Nothing hysterical about it, which bits do you feel are incorrect?
Politically we had no mandate for war, the public did not want it, not convinced?
Look at the crowds who greeted Chamberlain after the Munich agreement ("peace in our time"), still not convinced?
Look at France's treaty obligation to guarantee Czech borders, see how quickly they reneged on it, still not convinced?
Read Chamberlain's letters to his sister predicting the collapse of France if attacked, still not convinced?
Read Chamberlain's letters on how we needed to buy time and cross reference that with the date of the formation of the first Spitfire squadron, still not convinced?
We were not ready for a war in 1932, we were not ready for a war in 1939 or for that matter 1940 we were barely ready in 1941 and only started to find our feet in 1942, Churchill could not have taken us to war or tackle Hitler in 1932 as we had nothing to hit him with, we would have been viewed as the aggressor and the public would not have allowed it so soon after The Great War, still not convinced?
Read Hansard and Chamberlain's rebuttal citing "defiance and defence" hindsight is a wonderful when you can subtract the political climate in a social democracy at the time.
