It is necessary to understand the nature and application of human nature, and to create a "global democratic constitutional republic cosmopolitanism" in which human races have no war on the earth, eternal peace, republic, coexistence, co-prosperity, co-benefit and win-win. The rationalization of the world constitution's world government system accommodates different ideological and political systems and governs the world. Liberate nationalism and liberate the global political jungle, so that everyone in the human race can always have rational autonomy in life and live in peace and contentment on the earth.
