Nonsense. Lincoln's provocation caused them to fire on Sumter. There's no way around it.
Linclon's actions in reinforcing Sumter were consistent with his position outlined in the Indianapolis speech.
Consistent or not, they still instigated a war.
After that Lincoln pursued the war that was forced on him.
The invasion of Virginia was never forced on him. He did it on his own.
His only other choice was to give in to the confederate actions he saw as illegal.
Why couldn't he have tried negotiating peacefully? Why couldn't he have let them go on their own peaceful way?
The south brought death and destruction on itself through it's own reckless actions.
In other words, you are back to that same silly old argument - "the south made us do it"
