If he tries that route then he should be treated as an enemy combatant and tried and executed in GTMO.

Can't be, 'enemy combatant' isn't a category. There are lawful combatants, noncombatants, and unlawful combatants. In any best case, 0 could only be an unlawful combatant. See:

LOAC

Good thing you can kill wound or hold for war crimes any unlawful combatant.
