"There is no evidence that Chamberlain prepared for war with Germany - sm sources say "he must have known..." - if that is the case, he was lying to the British people when he said "peace in our time"
A shame you cannot read or understand what is above. Why do you keep repeating yourself

" Kingsley Martin’s column in the New Statesman shortly after the Anschluss suggests the willful opposition to even minimal defense expenditures that the Left exhibited throughout the decade: ‘Today, if Mr. Chamberlain would come forward and tell us that his polity was really one not only of isolation but also of Little Englandism in which the Empire was to be given up because it could not be defended and in which military defense was to be abandoned because war would totally end civilization, we, for our part, would totally support him.’
" the government of Neville Chamberlain made the crucial decision in late 1937 that Britain could only afford the buildup of a fighter, as opposed to a bomber, force, but it reached that decision because fighters were cheaper, rather than based on any belief in the efficacy of air defense. Churchill’s constant hammering on the lack of preparedness in the air and the importance of air defense supported what buildup did occur and provided much of the narrow margin by which Fighter Command won the Battle of Britain in 1940."

The labour party, as ever, sabotaging efforts for defence.
