That Jefferson Davis and company "could have been" linked to Booth is that. "Could have been". While folks "speculate" on this, the most important issue is, that Lincoln ordered a war that involved, the United States military to invade states that "simply withdrew from the union", to be attacked, it's civilians killed, their property seized, and their homes burned, with over a million casualties.
Re-Construction was actually "De-construction" of these states, AND THEIR POPULATION.
Had Robert E. Lee been fighting an "OFFENSIVE WAR" rather than the "DEFENSIVE WAR" he was fighting to "PROTECT SOUTHERN STATES", rather than "CONQUER NORTHERN STATES", and had he gone into D.C. when he had the chance, we would be living in a different United States today. Our "STATES RIGHTS" would not have been done away with as Lincoln most certainly did away with them, and most likely "NEGOTIONS" would have prevailed, and a BUSINESS AGREEMENT would have been agreed upon, rather than Lincolns attitude of "WE'LL JUST TAKE YOUR RESOURCES".
Lincoln's "EGO" saw it as someone "disobeying" the D.C. god. Lincoln should be viewed as America's "first socialist president", and Robert E. Lee should be viewed as a good, and moral man, whom misjudged his opponent, in that said opponent, would not see the insanity of himself, thru his own fog of power, and self rightousness.
