Chamberlain's Grandson?

Your name isn't Chamberlain is it? There were those in the late 1930s who said the same thing about Nazism and Japanese expansionism in Europe and Asia. World War 2 started for the United States when Pearl Harbor was attacked on December 7, 1941, but the war had been raging in the rest of the world since the mid-1930s. Isolationalism does not work. History has shown that it is a failure.
