I think we have such a big deal on the 4th of July because our nation was born out of revolution. Hence, the fireworks. We fought for the right to be free of what was perceived as the oppressive rule of the English. Our national identity was crafted. It didn't evolve, though surely there has been evolution since that day in 1776 when we won our freedom. That's why freedom is always featured as a theme in Independence day celebrations. It goes a long way to explaining, I think, the essential identity of my country.
