Enough past symbolism. U.S. Independence Day is also a good day to reflect on the paramount governance challenges of the present and near future. The U.S. War of Independence helped usher out the era of kings. Now is time to hasten the demise of the nation-state, born of the previous era.
One non-revolutionary (violent revolution, of whatever intention, is bad as it enables trolls) path forward is the creation and expansion of legitimately democratic super-states which submerge joining nation-states: the legitimate constituents are individual citizens, not the states themselves (contrast with the United Nations). The European Union is the only such super-state, and perhaps should be the only one, eventually submerging all current nation-states.
