Is Neville Chamberlain a bystander?

"Chamberlain believed that Germany had been badly treated by the Allies after it was defeated in the First World War. He therefore thought that the German government had genuine grievances and that these needed to be addressed. He also thought that by agreeing to some of the demands being made by Adolf Hitler of Germany and Benito Mussolini of Italy, he could avoid a European war."

"My good friends, for the second time in our history, a British Prime Minister has returned from Germany bringing peace with honour. I believe it is peace for our time...Go home and get a nice quiet sleep."
--Neville Chamberlain, 30 September 1938
