No, fantasy is the notion that Confederate military force which first provoked war, then started war and formally declared war on the United States, while supporting pro-Confederates in Union states, and then refused to seek peace on any terms short of "unconditional surrender" -- only fantasy could suggest that those Confederates were anything other than politically insane.
I have come around to the position that the refusal to evacuate those forts and the refusal to negotiate for a peaceable withdraw from them represents the start of the war.
Once you accept that someone is going to hang on to something that has no further value to them except as a casus belli, then you realize the intent was to have a war all along.
