It is up to Iraq to protect a visiting Iraqi-citizen's natural rights. Iraq may choose to do this with an international agreement, which we should hold our govt. to, if it makes such an agreement. But when a non-citizen here can be deported, he has no liberty, much less rights under the Bill of Rights, here in the US. Before we deport him, we can bug his apartment without a warrant, without worrying about any rights he might try to claim under the BoR. If that bothers him or his country, he should leave, or they should conquer us, if they can.
A visiting Iraqi citizen has an inferior claim to the protections of the Bill of Rights. That's all I'm saying.
No radical extensions of protections should be provided to just any lowlife, just because he happens to be inside US borders.
Similarly, I don't expect my natural rights to be protected by foreign countries I may be visiting. I might like them to, but they owe me nothing, unless their Constitution or laws say they owe me something.
Our Constitution was written for the posterity of the people who are OF the United States, not non-citizens who are visiting.
I don't know what else can be said. It sure seems to me that you believe that all that nonsense about natural law that pervades the Enlightenment--all that hogwash about men being "endowed by their Creator" should be flushed down the toilet to be replaced by the more profound and metaphysically sound notion of rights by citizenship.
As a side note, the so-called "right to privacy" extrapolated from the 5th amendment is both an absurdity and impossibility. Privacy is a great thing and I really cherish it, but it can by no rational construct be construed to be a right. There can be no right to ensure a lack information in the minds of men. Therefore compiling information on people is NOT a violation of their rights. Violations of rights must entail actions or coercion against person or property. Illegal government actions are those the Constitution doesn't permit. I therefore don't see how compiling information on people is illegal either.
So, perhaps your real issue is in extending the privileges we usually expect to the category of rights in the case of aliens.
