Dictatorship, iron fisted, with the citizens taught to believe I am god from birth, that I give them the air they breathe, that I am the reason for life. Make them love me. Then, we begin invading to expand our nation, we kill every adult not willing to pledge to my godhood, the orphans put into academies to be re-educated for military use.
Keep close allies with superpowers because the children who don't pan out as military, will be used as cheap labor in american corperation's factories.
Join the U.N., cause friction between allies, act as intermediary to soothe things over in a public way, begin buying stock in the corrperations who use my factories, become major shareholder in them in a few years.
Start a space program, volunteering for my country's first manned mission, take a few years worth of supplies.
Release all the nukes
Enjoy the pretty colors
The world wont end in a whimper, but a bang!
