PW Botha, former head of state in South Africa, recently passed away. His death has provoked diverse responses, which all point to an underlying lack of closure on the subject of crimes committed under apartheid in South Africa.
I agree that the US hardly has the moral credibility to lead the international outcry over North Korea's nuclear weapons testing program. I also agree that there seems to be some confusion on the part of Western countries, where their "interests" and the “best interests� of the rest of the world are taken to be always congruous. However, my fear of your arguments is that they lie too close to a crippling moral relativism.
The question of exactly whose "peace and stability" is threatened by North Korea's action is certainly valid, but might be of less importance than other valid reasons for putting diplomatic pressure on North Korea. For instance, Kim Jong-il, a reclusive and unpredictable autocrat, is audaciously pursuing a nuclear weapons program and living a lavish life while his people continue to starve, neither of which, in my opinion, promote world safety or the welfare of the people of North Korea.
I would disagree with the last comment. I think we can all agree that children should be raised in family environments, not orphanages. So if Madonna gets an ego boost by adopting a child, should we really care? Similarly, if Madonna adopts a child in order to get an ego boost, we're no worse off, as long as the child actually gets taken care of.
