Essentially America has died. The question, at this point, serves only an academic pursuit. In pursuit of that however; the root cause of Her death can be traced to the agenda found in the UN Charter and the Marxism advanced and endeared by our politicians in the Declaration on Human Rights. This is the document that replaced the Bill of Rights. All of the social unrest and conflicts from the 1940's can be traced directly to thoses documents and to the many treaties that were born from that document. I would invite your inspection of that literature, which is readily available and proudly dispalyed on the UN web site.
To answaer your question---destroy the UN Charter.
