The world is so much easier to manage and control by a single dominant state when it is subjugated to a totalitarian monism of absolutism, even when said democracy is in violation of the most rudimentary principles of freedom and thereby in actuality fundamentally incompatible with the evolution of all of humanity, including our own, and regardless of culture.
The latter being the exact reason why we must reinvent the operating system for humanity to embrace the relativity of plurality borrowed from the laws of nature that have already encircled the world for some 3.5 billion years. The rules all humans are irrefutably subjugated to.
There is a fine line between world leadership and control. A totalitarian monism as the ultimate of power we shall not grant anyone.
