holocaust prevention?

in reality I believe that we should get involved in the prevention of genocide or the intervene it since it is a violation of basic human rights. In addition allowing certain nations independence such as Sudan which with the current government would not allow. In addition we the U.S Support the UN united nations which are the people that deal in this type of thing, so we need to promote the UN to do this . Sadly I also believe that an individual country cannot help them even if the people  wanted to, because of the lack  businesses interest in the area's  which was one of the causes for the U.S being located in Afghanistan, which we thought was to protect the people there but it was in reality only for the resources. In these areas the companies that supported the government have no interest and little money to be made  in these areas, therefore I believe they will not provide support, in the end it comes down to one thing greed.
