Will this video finally settle the debate? "Was the Civil War About Slavery?"

Colonel James T. Seidule published a YouTube video on August 10th that already has almost half a million hits.

About the video: What caused the Civil War? Did the North care about abolishing slavery? Did the South secede because of slavery? Or was it about something else entirely...perhaps states' rights? Colonel Ty Seidule, Professor of History at the United States Military Academy at West Point, settles the debate.
