There are many people who balk at the idea of the United States government running to help everyone who is the victim of a disaster. From the people who were affected by the earthquakes in Haiti to the people who were victims of the tsunamis in Asia, they are always ready to run to the rescue of those in need. Some people say that they need to worry more about what is going on here and less about what is going on in other parts of the world, It is clear that they are not wise about how things work.
The United States is a superpower in the sense that they have many resources available that some countries do not. What in the world would they look like if they sat around sitting on their hands and being selfish while other people in the world have problems? The next time we needed help from an ally, they would be far less willing to be of assistance. In order to remain on the good side of those that you may need at some point in the future, it is necessary for you to help when needed. It is really that simple.
