Takes two have a war, Jefferson Davis was game for the fight. He even pulled the trigger first.
Sure. The attacker, and the attackee. The one who goes to the other's homeland and tries to impose their will is the attacker.
The Attackee generally doesn't have a choice in the matter. When the Attacker decides to have a war, the attackee has no choice but to go along with it.
He even pulled the trigger first.
Lincoln pulled the Trigger first. No warships, no war.
Again, almost his entire staff said this would cause a war. Anderson also said this would cause a war. The only people who don't seem to think this was a provocation to war are modern people who want to justify Lincoln's deliberate sending of Warships with orders to use force to defy the CSA's jurisdiction.
Lincoln made the decision to cause a war. Davis' act was a response to the Lincoln decision. Lincoln was cause, Davis was effect.
