The crucial Moral wars versus unimportant Morale & Military wars

We are all so used to wars fought between nations, where it is expected that every citizen in each nation at war will not work to defeat their country's war effort, that we forget about the situation in other forms of armed conflict.

For example civil wars and violent revolutions.

These are fought inside individual nations and we fully expect that these same national populations to be sharply divided among various ideological positions - indeed that is partly how we define civil wars and violent revolutions, as opposed to say widespread incidents of armed banditry.
