I would be a wise and fair emperor.
First, to stimulate the economy, I would commission a statue of myself, made of solid gold, depicting me as a sword-bearing general on horseback, and big enough to make the Colossus of Rhodes look like a midget.
Then, to unite the people, I would abolish all TV networks, replacing them with a single channel dedicated to me, broadcasting 24/7 propaganda attesting to my greatness. Any TV channel that I enjoy would still be allowed to exist, provided they broadcast exclusively to my extravagant palace from which I would rule.
Finally, to establish world peace, I would abolish all national armies and create a legion of invincible mechanical death walkers, armed with death rays and nukes, to crush all resistance at the first sign of dissent. I would even have a personalized death walker I could pilot myself, so that I could destroy any rebellion personally if I wished.
Yes, I would be a very wise, very fair ruler.
