They may not have written it explicitly into the constitution, but there’s a neat little trick about the Declaration of Independence that applies to every human on Earth as best as I can tell.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

If those rights come from God, and I believe they do if a man carries himself uprightly in godly virtue, then every man can enjoy those rights by virtue of existing, and they can not be taken away.

All that can happen is that a government can cease to acknowledge and respect them, at which point they have openly declared their status as a criminal organization opposed to God himself.
