Whenever something bad happens – Iran moving closer to acquiring nuclear weapons, North Korea firing another missile, civilian deaths reaching another grim milestone in Syria's civil war, satellites revealing an alarming rate of polar-ice melt – some official or observer will call upon the international community to act. There is only one problem: there is no "international community."
Part of the reason stems from the absence of any mechanism for "the world" to come together. The United Nations General Assembly comes closest, but little can be expected from an organization that equates the United States or China with, say, Fiji or Guinea-Bissau.
To be fair, those who founded the UN after World War II created the Security Council as the venue in which major powers would meet to determine the world's fate. But even that has not worked out as planned, partly because the world of 2013 bears little resemblance to that of 1945. How else could one explain that Britain and France, but not Germany, Japan, or India, are permanent, veto-wielding members?
