Why America is to blame
Throughout the movie, and right into popular discussion, as well as during and after the actual event, the question was brought up incessantly, why isn't America helping? And ultimately, it's America's fault this was allowed to happen. If we look at America's track record for helping other nations it would magically seem like a 100% failure rate according to the same people who blame America for not stopping this genocide.
But let's imagine the US did intervene. First, for your story to make any sense, you have to admit America has a right and duty to go into foreign nations and kill their people under certain circumstances (yet without being asked by that country's government). If you can't admit that, you're a hypocrite and a liar, only out to blame America. Because nothing short of entering the nation and killing its people would have possibly done any more to stop the genocide.
Then you have to admit that American lives are worth less to you than other human lives, and that you think it's OK for some 17 year old boy from Nevada to die on the streets of Kigali 9,000 miles from home while shooting children (child soldiers) in their own country. If you can not accept this, then you are a hypocrite and a liar.
Then you must admit that in order to stop a national genocide spanning thousands of miles and millions of people, it would take hundreds of thousands of American service members. And because this genocide from start to finish lasted about 100 days, those service members would have had to leave the US immediately upon hearing of a civil war (because the facts took time to come out) and that the US should always mobilize hundreds of thousands of service members to go anywhere on Earth and kill their people the moment word gets out that a fight has started because it might be a genocide and we wouldn't know it yet. If you can't agree to this, you are a hypocrite and a liar.
Anything short of immediate full scale war on the part of the US, and it becomes America's fault. If they had merely sent in special forces as some of you morons suggest, they could only possibly take out some leaders and possibly evacuate tens of people. If they had tried to build up a proper invasion force for effectively ending the genocide, it would have taken weeks, possibly months, but that would be "stalling" and you would still hate America for what it allowed to happen.
You are children, with small minds and you have no idea of the things you truly ask for. You want magic and miracles and fairy dust. You want Americans to die immediately and without regard for their own safety to help people they've never met thousands of miles away in a country that neither invited them, nor ever liked them. Like Somalia, where people laughed and cheered as American bodies were dragged through the streets having been killed for trying to feed starving children. You all disgust me. None of you are worth the breath you waste or the energy you expend blaming America for everything it does and doesn't do.
