What If the Confederacy Reunited Today?

So just suppose that Abraham Lincoln had let the South go. What if he had said: We part as friends. We hope to reunite as friends. There will be no coercion of the Southern states by the people of the North. No state shall be kept in the Union against its will. Such a turn of events would be contrary to every principle of free government that we cherish. But we ask the Southern states, to which we are bound by mystic chords of memory and affection, that they reconsider their action. If not now, then later, when the heat of anger has subsided, when they have seen the actions of this administration work only for the good of the whole and not for the partisan designs of a few; when this administration shows by word and deed that it is happy to live within the confines of the Constitution, that we will admit of no interference in the established institutions of the several states. I trust that by our demeanor, by our character, by our actions, by our prosperity and our progress we will prove to our separated brethren that we should again be more than neighbors, we should be more than friends, we should in fact be United States, for a house united is far stronger, will be far more prosperous, and will be far happier, than a house divided, a house rent asunder by rancor, a house that undermines its very foundations by separation.
