Could you provide a link to the relevant executive order stating this? If it wasn't obvious I'd like to read it. Like not joking, I can't seem to find anything official which makes this definition in a legally binding way.
Okay so the important thing here is that there are protections for U.S. Persons which the rest of the world does not enjoy. If you are a citizen of the United States of America none of what your speaking about applies as there are overriding edicts. However, if your not a U.S. citizen then well, you don't enjoy the protections of the U.S. Constitution unless you fit a specific set of conditions. Sorry. Have you considered immigration? I kid. No you have to look to the laws and polices of your local government (if you have one) to determine what protections you have (if any) under any possible treaties with the U.S. your government might have. I have a hard enough time just trying to keep current on U.S. Law to intelligently respond to international policy.
There can be exceptions to this like Treason as committing treason is a felony and results in loss of many of the protections afforded by our system. The conviction in absence is kinda complex in this regard. Further, aiding the enemy is sufficient ground to “cap yo ass”. For example, lets say we were in a war and you decided to wear the uniform of the enemy and shoot at U.S. Troops. You will likely be treated like an enemy combatant even though your a U.S. Citizen.
