If you are given chance to rule the world..what will you do and how your rule it? ;)

I'd create one set of laws for all of the world to follow. I would allow people to keep and practice their cultures and their religions, so long as they are not used to harm another. Church and government would be truly separate, as those who serve a position of leadership would make the sacrifice of being able to practice their religion, but not publicly or even allow others to know what their religion is. (I don't like when someone's religion is used as a selling point to get votes.) Yes, I would make democracy the standard for the world. I would do away with the idea of nations. We would no longer be American, Chinese, French, etc. We would simply be human.
