Casper,

Could you explain your question a little bit more.  I think I know what you are saying but do not want to mis-respond to your comment.

Certainly, this is not just a U.S. issue alone and it is certainly not even an issue that has arisen since the concept of nation-states.  This is a rather timeless question always faced by followers of Jesus living in this world under and in political, social and cultural structures of power.
