I don't understand mentions of "civil war" in the public lately (there's even a Hollywood movie about it).
There is only one party controlling the armed forces. I also doubt that any high-ranking officers would take the troops they command out of the command structure and then even order them to attack the government and other troops.
Not to mention that the new administration did some cleanup among the ranks already.
The chances for enough, or any, troops breaking away from the command are very low, no?
So who is going to fight that "civil war"? It looks to me like the government has overwhelming power. At most I see some troops refuse orders to shoot at the American people, or at other troops.
Armed civilians with their puny little guns and little organization are right out as soon as any part of the military joins a fight, that's why I only mentioned the latter to begin with.
