Why did many people feel giving in to Germany at Munich was a good idea?
Because at the time the British people did not want to go to war with Germany to save the Sudetenland which had a high proportion of German speaking people anyway. Neville Chamberlain was an honourable trusting gentleman who was completely taken in by Hitler’s promises that his territorial ambitions would end there. When Chamberlain returned from Munich waving his piece of paper he was hailed a hero, he was horrified when soon after he realised that he had been duped and could hardly believe that Hitler would lie to him. Curchill replaced Chamberlain not because of any failings on Chamberlain’s part except the country needed someone just as ruthless as Hitler himself to do what had to be done.
