American law. I could give a damn about foreign or international law unless I'm a guest in a foreign country. I've been stationed all over the world and I understand following the rules of a foreign country. Again, that's not the issue for me. When you invade my country I don't care about your rights--civil, international or intergalactic for that matter. All I care about is sending you back. Once you get there you can have a chat with your government representatives and tell them why you invaded a sovereign country.
