An interesting discussion of secession from a white nationalist perspective from The Occidental Quarterly.
Four years of bloodshed proved that the South was not strong enough to secede without the permission of the North. It steadily and gradually lost, militarily, a battle that it had already lost politically before it seceded. Had the South been strong enough to secede without permission, it would also have been strong enough to defend its political interests without seceding.
Secession is an attempt by the politically weaker of two parties to solve, by leaving the field, a political problem that it is too weak to solve, either politically or militarily.
Only the weaker party in a political conflict would want to secede. Only the stronger party would be strong enough to secede without the permission of the other. However, the stronger party would not want to secede because it could force the weaker party to do whatever it wanted.
Covington suggests that military disaster at some distant part of the empire might make the United States too weak to hold on to the Pacific Northwest in the face of guerilla warfare. Maybe so. But this would give the homeland the kind of temporary safety that a Thanksgiving turkey enjoys.
Any place where a secessionist might want to live would be too valuable for the larger, stronger party to give up.
The Pacific Northwest, in particular, is far too valuable to secede in peace. It has valuable hydroelectric power, in a world hungry for cheap energy. The Columbia, its most important river, is 1,243 miles long. Puget Sound gives the Pacific Northwest well-sheltered, world-class harbors. It has a major naval base. Nuclear submarines silently travel its waterways.
