Did anyone ever answer your questions about Gitmo?
One of the points that is being missed is the sheer illogical nature of claiming that sending supplies (not reinforcements) to an established fort on Federal land to a strictly defensive garrison is a casus belli.
If anything, the firing on the Star of the West and the seige of Fort Sumter were just cause for Lincoln to attack. But he refrained until after the attack on Ft. Sumter. Fort Moultrie had already been abandoned by this point as well.
No, but honestly I didn't expect them to.
