&quot;What you described is mostly descriptive while I argued purely normative&quot;<p>A normative claim that the world &quot;should&quot; have one government when there&#x27;s no way to make it work is just fantasy. Nonexistent options don&#x27;t figure into the moral calculus. If the EU can&#x27;t be made to work it certainly can&#x27;t be extended to the entire world. You think the stress of the EU is going to be lessened when it is outvoted on every issue by Asia?<p>Every major centralization of power right now is under huge stress and in serious danger of flying apart at the seams in the next couple of decades. There&#x27;s no current &quot;world government&quot; option.
