Answer:
The failure of the policy of appeasement was in that Hitler was unappeasable.
Step-by-step explanation:
He didn't want some balance of power in Europe where Germany had a higher edge, he wanted an entire German-ruled Europe. Chamberlain (the British prime minister) gave into Hitler's demands of taking over Czechoslovakia to attempt peace at the Munich Conference. This approach came to be known as appeasement or the policy of weakness.
