So a reckless head-first charge into a bloody war is standing up for "what is right" now? Curious.
Lincoln's cabinet warned him at length that Fort Sumter was a VERY volitile issue that had to be handled with extreme care so as to avoid unnecessary bloodshed. Not only did Lincoln launch a careless and sloppily organized naval expedition, he also sent it under the one set of directions that were sure, more than anything else, to provoke an immediate war there. Actions of this sort seem to be a recurring theme of the Lincoln presidency: of all the different courses he could have taken he picked the most reckless and extreme one.
The war was initiated by the Davis regime. Had Lincoln landed supplies at Sumter then what? How would that have constituted a threat to the confederacy? Was Charleston blocked? No. Were the people in danger of being bombarded? No. Was the Davis regime threatened in any way whatsoever? No. There was no reason at all for Davis to open fire at Sumter except to begin the war that he wanted all along, the war he needed to induce the other slave holding states into the confederate fold.
