Sudan: Civilians Driven Into Camps, Then the Bush

In the comments of this article, somebody said "Why is the US government not doing anything about this situation?" I want to ask that person then why US government should do something about the issue that is happenning out of the nation. US government doesn't have direct responsibility to help other countries' problem. And people including myself don't know every single detail of the occasion about this process. Sudanese government might not want US's help (just a possibility) or US has no right to do so (another possibility) or US might lose its own people too much, in other words, what it takes is greater than what it earns (the other possibility). Most people don't and can't know all the factors and are complaining about what they just see which is just a tip of an iceberg. In terms of legal process and international or national process by government, there is no such spot where ethic dominate practicality or viablity, in my opinion. It sounds really funny when people criticize government and what they do when they know not much of what's going on in that process. It is even funnier that I am criticizing that kind of people while I don't know what they think when they write those.
by the way, the same person as I mentioned up top also says "Is OIL more important? Are african lives worth less than Irish or Jewish lives?" And I would say Yes depending on the occasion. Life of human being doesn't necessarily have more value than oil and not every human being is equal to a person's perspective. disregarding race, gender or any kind of possible discrimination, a person tends to value his or her family more than stranger his or her friends more than those who live in a different continent. From there, inequality already exists. Equality in terms of indiscrimination on certain basis is somewhat needed but shouting for equality of all human being is simply bullshit. I mean, some people might be able to see everyone equally but that doesn't make everyone equal. I don't want to get into much detail about equality because it takes too much space if I write while I could relatively easily explain through conversation.
