Well, rights are concepts created by, granted by, and enforced by, humans. There really are no such things as "god given" rights. An International body set up to enforce "basic human rights" violations will only work if it has the teeth to enforce it's rulings and what if the subject is a citizen of a non signatory nation? And how far does it go? Europe is using blackmail (IE the death penalty issue) with some nations who want to join the EU. There have been proposals put to the UN to pass resolutions abolishing gun ownership by private citizens worldwide but obviously aimed at the United States which clearly impedes on American national sovereignty. It is becoming more and more clear that International bodies such as the UN are becoming less and less effective as time goes by mainly because it's members are stodgy bureaucrats. I think that international courts (which the US fortunately doesn't recognize) are a bad idea. It's better to let nations hold people accountable according to their own laws.
