Recently I wrote an article asking if the US just disappeared, what the world would be like. Well, I think it's fair to say that someone should be running the world, and I think it shouldn't be the US.
What the world needs is to be run by a United States of Europe.
For better or worse, the modern world is already a macrocosm of Europe. Except for very few examples, historical European expansion has touched, manipulated and transformed the world into what it is today, it is only fair that it should decide its destiny.
Put together, a fully United Europe (including Russia), as one country, would be by far the largest economy and hold the largest and most developed military in the world.
From the influence of Alexander the Great, to the Roman Empire, to the many Spanish colonies, to the mighty Russian frontier, to the "sun never setting on the British Empire," our world languages, cultures, systems of government, legal codes, economic infrastructures and commerce, etc. have a founding basis in Europe.
In a way, us outliers are all Europe's sons. In this fragmented and chaotic world we live in, maybe it's time dad should come back in to run his house...
A world state has been the dream of Western Civilization, and most agree the US wouldn't be the appropriate overlord. What about Europe?
