No violation. If pushed, Jackson would have sent troops. The reality was both sides were bluffing and looking for a way out in 1832. But the idea of disunion was on the table. As time went on, Palmettos became comfortable it.
In 1832 South Carolinians realized they acted alone in threatening secession.
They resolved that next time other states must go out with them.
So by the 1850 Fire Eaters worked throughout the South to promote secession.
But they were quieted somewhat by the Compromise of 1850 and elections of Democrats in 1852 (Alabama Senator King VP) & 1856 (Kentucky Senator Breckenridge VP).
Then Bleeding Kansas, Sumner's caning, John Brown & the rise of Republicans roused Fire Eaters to work again.
By 1860 they were a major political force across the Deep South.
