Who invaded who? Davis made his mistake with Ft. Sumter, but nobody died from combat there. Lincoln did not have to send troops down the road to Richmond, which killed several hundreds of men on both sides. Both sides could have forgotten Ft. Sumter and chalked it up to the stupidity of Davis, but neither side could walk away after Lincoln’s foolish march into Virginia.

There is that little matter of the confederate declaration of war on the US.
I guess we should have ignored Tojo’s mistake at Pearl Harbor, rather than fighting. Oh, that little mistake at Bataan too. Submarine war? Another mistake. Just ignore it. German declaration of war on the US? Ignore it.
Yes he did - after the south declared war against the United States. The debate, the friction, and the war were the inspiration of the southron slavers and Lincoln merely responded to their actions. If anyone is to blame for the misery it is the slavocracy.
