At left we see why Lincoln would have done well to let the Confederacy cede from the Union. He could have simply written a letter to Robert E. Lee stating:
Keep your slaves and your land…for now. Wait until you experience the effects of near-zero industrial and military technology development and the civilized world’s refusal to trade with you barbarians. By the end of the 19th Century, a stiff breeze will blow you away. Maybe some future U.S. president will invade you with a troop of Boy Scouts with slingshots, or maybe a handful of banditos will ride up from Mexico.
