Continues to collect tariffs that they feel is due them which is what started the war in the first place
The war was unwinnable by the South after May 10,1863. Lee's military decisions also pretty much guaranteed eventual defeat. Rather than adopt Jackson's strategy which would have raised hell in the North he and Davis preferred to remain on the defensive and fight headlong battles against a more powerful enemy. Jackson never fought a headon battle if he could flank the enemy or attack from the rear. He understood that to win you had to force the enemy to attack you. Defensive positions brought such incredible firepower to bear that attackers rarely won.
Lincoln was so far superior a man to his opponents in every way that his strength of character held the Union together until military genius arose in the form of Sherman and Grant which could counter Jackson, Stuart, Forrest and Lee. Most of the other generals on both sides were pretty incompetent.
