One of the reasons this question is so facinating is because how you view it depends a great deal on what you mean by justice and how what justice is is determined. Is justice what a court says it is. Is there justice of the kind that Plato might consider, a perfect form to which we aspire. Does it come from God. Is it how decent people, people who have transcended the false self, act and judge. What is justice? It would seem that what we call justice evolves overtime even if it is something absolute that we move toward. So, since we all prize justice, how we see the issue depends a great deal on what we place faith in. I think that all people are the same, that we are all reaching for the same rainbow. So I see no reason why an international court cannot approximate or ever surpass our current notion of justice. But men are petty and small everywhere too. So this whole issue will evolve and change and continue to provoke thought all over the world. But if our system is great, then we need to be players and contribute what good we have to offer. Justice will like that, I think.
