Lincoln's cabinet told him the sending of those warships would start a war. Major Anderson said it would start a war. The person who is responsible for starting a war is Lincoln, and no one else.
Again you are the one making up facts. Lincoln sent ships to resupply a fort, with orders only to respond with force if the south attempted to stop them by force. The rebels could have simply let them resupply the fort but decided to start shooting instead. Trying to characterize that as sending “warships to attack the South” is a lie no matter who correctly predicted the southerners would respond with aggression. You are clearly beyond accepting that reality, but nobody but a handful of neo-confederate kooks really believes your spin. You cannot change who fired the first shots.
