I carefully said "fomented" for a reason.
Lincoln resupplied Fort Sumter, despite warnings not to do so. The garrison at Sumter was in place to discourage imports into the port of Charleston, which was a provocation for war.
Lincoln had plenty of chances to make peace with the South, both before and during the war. He ignored all overtures.
I know my history. Respectfully, perhaps it is you who should venture out beyond the simple public school revisionism of American history.
Warnings from whom, the enemies of the United States? He was the president...
That is like saying the USA provoked the terrorist attacks...
