Was appeasement a mistake for Britain after World War 1?

Answer 1

Yes, the appeasement policy of Britain helped Hitler gain the stronghold over Europe and ended with the blitzing of London. The first aggressive land grabs of Hitler were allowed, since British and other leaders felt it was something he had a right to do, and if they ignored it, he would stop. He didn't, and by the time they entered the war after Hitler's invasion of Poland, he had gained too much power to be immediately stopped.
