Yes, they are. They are covered as nonuniformed combatants--terrorists. Guess what? They have no rights. Period. You can kill them at will.
The Geneva Conventions recognized that if armies degraded into general terrorism, it would not be to civilization's benefit. Therefore, terrorists, spies and sabateurs should be treated harshly to discourage such behavior.
Now our government wants to afford them the same protections enjoyed by uniformed combatants fighting on behalf of national identities--very foolish... and dangerous.
