This first hand account of the Yugoslavian Civil War of the 1990s gives us some military lessons in how such a social fragmentation and civil war may play out here in the U.S., as well.
“Key takeaways: The number of soldiers in active fighting was low on any side. Clans are best in defending their territory but ineffective in attack. If you occupy a territory you cannot hold it unless people originally there leave or die. Trust that your flanks won’t desert their position is crucial, which would mean that homogeneous nation is essential for a successful recruit army, especially for defense.
We can draw a parallel with western Europe where ghettos can be equated to valleys and people in ghettos show similar characteristics to clansmen. Croatian victory shows the path, coordinated attack on all valleys at once and established corridors for retreat of the civilians.”
