World War II was a change agent in history like no other. It can best be understood in pieces, barely grasped as a whole. In this audio narration of Chapter 24 of The American Yawp, a U.S. History Textbook available as a free, modifiable educational resource, I narrate the American history piece. The chapter sets it within the context of all other pieces. I am that rare narrator who is also an historian. I have taken the opportunity to make a few important corrections to the text, where I have perceived errors, and have added to it where I see important omissions. I, too, offer the text free to my listeners, in the spirit of educating my fellow citizens and improving their lives. If you enjoy this recording, please let me know by emailing me a sentence or two to this effect at [email protected]. I can track clicks and downloads but this is my only way of determining if anyone is actually listening. Happy listening to all.
