This week on History Happy Hour:  According to US Secretary of War Henry Stimson, the "most shocking single event" of World War II was not the Japanese attack on Pearl Harbor, but rather the fall of France in the spring of 1940. In recognizing Vichy, the US not only demonstrated panic and moral ineptitude but also nearly ruined the alliance with Britain.

Chris and Rick will explore this topic with Michael Neiberg, author of When France Fell: The Vichy Crisis and the Face of the Anglo-American Alliance.
