Answer:
The death and destruction of World War I was so
horrible that it was called “the war to end all wars.”
Yet, the agreement to end World War I did not resolve
the problems of the world and, according to some
historians, lead directly to the next catastrophe:
World War II. The major causes of World War II were
numerous. They include the impact of the Treaty of
Versailles following WWI, the worldwide economic
depression, failure of appeasement, the rise of
militarism in Germany and Japan, and the failure
of the League of Nations.
