Why did channon claim appeasement was the right policy what if any evidence did he use to back this claim

Neville Chamberlain became Prime Minister of Britain on 28th May, 1937. Over the next two years Chamberlain's Conservative government became associated with the foreign policy that later became known as appeasement. 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.  Joachim von Ribbentrop was ambassador to London in August, 1936. His main objective was to persuade the British government not to get involved in Germany territorial disputes and to work together against the the communist government in the Soviet Union. During this period Von Ribbentrop told Hitler that the British "were so lethargic and paralyzed that they would accept without complaint any aggressive moves by Nazi Germany."
