What difference can one person make? Whoa there, a lot more than you could ever imagine. Take for example the Mongols. Yeah, the Mongols. What's so great about them? Well, they weren't exactly "great" in the sense that we would have liked them to be, but they were very influential and powerful. I want you to know that the mongols were one of the shortest people in Asia. They did measurements according to the size of the hand which is about 4 inches ( I believe from the thumb to the outer edge of the hand). That is quite the small measurement. Yet, they accomplished the task of conquering 3/4 of Asia, including part of Western Europe. Sure, they took it by force, killing and pillaging as they went, but they were skilled soldiers, horsemen, and farmers. They lived in a land with little water and poor soil, yet they still grew crops. They became an educated culture that was admired (in some aspects) and feared.
I remember a line quite well from the movie The Lord of the Rings: The Fellowship of the Ring, "Even the the smallest person, can change the course of the future." I strongly believe that a few people can change the face of the world, for good or evil. Fifty-six men changed the western world in a matter of a few years. Who says we can't have something similar happen like that again. We're America and we know how to fix things and make what is wrong, right! We just have to be willing to take on those tasks.
