Do you do that low grade comedy act for money?
There was zero “Threat,” the industrial revolution was in the process of demolishing the slave-based economy, and could have accomplished the conversion without mass bloodshed.

Now that's comedy! Low grade, but still comedy.
Now militarily: look at the map in post #52 above.
Confederates claimed & fought for several Union states & territories.
In what conceivable way was that not a threat?
As for "mass bloodshed", that was the Confederates' choice and they refused to stop fighting on any terms better than "Unconditional Surrender".
