Stupid People

I am amazed at how many stupid people there are in this world. Why do we strive for so much pain just so we can call ourselves the "official" leaders of the world. Of course everyone in all nations want to be the leaders of the world because understandably people want the world to go their way. Everything would be perfect if all people just thought like "us" right? Well no. But that is no reason to start a war. There are certain circumstances, The Great War being one of them. But to oppress some country just because we see them differently is just ignorant and stupid. Unfortunately it does not take very smart people to start wars. Furthermore, it ONLY takes intelligent people to end them. How can we keep up this terrible game of king of the hill? If aliens were to come to this Earth, i am not sure they would even want to stay. They might even see the Earth as a planet where the majority of the inhabitants just lull about and fight all the time. The Earth to them would be just one giant civil war. I personally don't know how to end these problems. You could say i am ignorant because i am. But how many people really know they are just that thing?
