This post will likely be shocking to some of my readers who see the Civil War as the just war. For a more extensive re-examination of it, read Thomas DiLorenzo’s The Real Lincoln.
For anyone who thinks the Civil War is justified by the abolition of slavery, I will say that slavery was abolished peacefully everywhere else in the world (see Emancipation Reform of 1861 in Russia). There was no reason to kill 600,000 young men to do it here.
