I think the point is that whether it be Kony or someone else, it's no secret this kind of thing goes on in Africa. It's no secret this kind of thing goes on in many places in the world. The "we have to start somewhere" statement is key.
Regardless of the man or the country, the object is to get nations that will fight wars over oil to at least show some interest in the well being of mankind. Of course I don't believe this is solely the responsibility of the U.S. Key statement #2, "this affects everybody". Isn't this how Hiltler got his start? The world pretending something wasn't happening...how did that end up? Oh right, a world war and millions of dead people before all was said and done.
