Anyone who participated or assisted the occupying power is classified as an enemy combatant and only due rights under the Geneva convention.

Fun Fact: Anyone who swore an oath to protect and defend the Constitution and who then becomes an enemy combatant of the United States is literally entitled to NO rights at all, citizenship revoked, etc.

Now as a practical matter the white hats are good people, so they will accord humane treatment to these, the worst of all traitors. But they don't have to.

I would submit that honoring human rights, such as food and water, reinforces our status as a moral society.
