This is the premier Civil War historian in the United States. Dr Bud Robertson. He is a Southerner and a staunch Conservative. He also does not have a butt munching slobbering man crush over Lincoln and teaches the truth about the Civil War.
All wars are over two things at their heart. Who is going to control Property and Resources.
Things like Slavery, and the Jewish Question and protecting the Holy Lands are always rationales for helping the cause of "controlling" others property and resources.
