Answer:
Appeasement : the action of satisfying the demands of an aggressive person, country, or organization: a policy of appeasement.
Explanation:
Why did England and France choose this path? : The main reason why Britain/England and France embraced the appeasement policy was because they did not want the whole of Europe to be dragged into a world war by Hitler. It was a policy being persued due to the lessons learnt from world war one.
Why didn't it work on Hitler? : Essentially the Policy of Appeasement did not succeed with the nations it was designed to protect: it failed to prevent war. The failure of the Policy was largely deemed on that Appeasement was misconceived; Hitler’s ambitions to increase Germany’s borders and to expand Lebensraum, stretched much further than the legitimate grievances of Versailles.
