How would World War II have turned out of the Nazis had successfully developed Nuclear weapons? And what does a small town in downstate Illinois have to do with having prevented that from happening?

Larry Potash digs deep into military history in this Backstory segment and the crucial role a pastor from a small town in Illinois and others played in a long-lost World War II operation.
