US Intervention?

It seems to be such a difficult question to respond -- "Should the United States get involved in countries that are possibly facing genocide? "; yet, I find the answer rather simple: absolutely. I can understand that a country can not always go out of its way to help another, but in the case of such a powerful and influent nation, as is the US, there is no excuse. What is the point of being prosperous when others around us are suffering? I believe that we are one, the whole world, and if we do not help each other in times of need, who will? If we have the opportunity in our hands to aid the weak and stop abuse, we should take the risk. I find myself very passionate when thinking about the time of the Holocaust. I can not understand how such numerous of innocent people were hurt and killed without previous intervention. If only I would've had the power to take all that injustice away, I wouldn't have hesitated in acting.
