For the outbreak of the Second World War

Do you think the leaders of Great Britain, France, and the United States between 1918 and 1941 deserve a share of the blame for the outbreak of the Second World War? Explain.

(The Thirty Years War, 1618-48, was a series of conflicts that grew out of the struggle for political and religious control in Central Europe. It was the deadliest European war prior to WW1.) Is this assessment fair? Why or why not?
