Jacques, thanks for sharing that link and I'm upvoting you. But you know what's funny? I have almost exactly the same set of premises of as that piece, but I come out to almost exactly the opposite position.
> The United Nations now and world Government eventually must serve one single goal the guarantee of the security, tranquillity, and the welfare of all mankind.
I think a world government would rapidly become filled with the most politicking, vicious, corrupt, oppressive people unless it was incredibly decentralized and powerless - I don't think you can have a large, powerful government wtih broad-sweeping powers and no opposition that is kind and benevolent. The only large governments/empires in history that were secure, tranquil, and with high levels of general welfare were decentralized.
Every powerful centralized government example I can think of committed all sorts of gross and widespread abuses - I think this is because once you create a mechanism for unchecked power, it inspires the most ruthlessly ambitious power-hungry people to attempt to control it. Those people eventually find themselves their way into high positions - democracy or not. Many brutal madmen believed they were doing the will of the people, and were sometimes legitimately elected. When you create a huge unchecked power structure, you're creating a bright light that attracts the most vicious sort of moth. Eventually one comes into power, and all hell breaks loose. Decentralization seems to be the only way in the long term, even with the equilibrium costs of a minimal defensive military force and coordination problems.
