Firing on federal property is ok? Firing on federal soldiers is ok?
Lincoln had no choice but to defend federal property and personnel.
WHAT “was working well”?
Blockading a Southern port is ok?
Occupying state property while training guns on the unarmed citizenry is ok?
Interrupting peaceful commerce in free ports is ok?
Sending secret armed missions to Southern ports to force entry is ok?

Look at a map sometime, FRiend. Ft Sumter is in South Carolina. Now go open a history book. SC was the first to secede, and did so on 12/20/1860. Following this several other states seceded. The Federal government of the remaining Union states withdrew their forces and materiel from every base in those seceding states over the following months... but not Ft Sumter. They were invited to peacefully leave SC numerous times, as it was no longer under their authority. Given their final requests, and refusing to leave... and it being a military fortress... the PROPER AUTHORITIES OF SOUTH CAROLINA WHO OWNED THAT LAND had no choice but to remove the foreign invaders by force of arms.
Lincoln himself offered to withdraw the troops from Ft Sumter if Virginia would not secede. source
There is no other way to view this event, unless you simply enjoy ignoring facts and history.
