The world is yours, you have an army of battle droids or demons or just people, whatever you choose, but what now? Will you rule the world as an iron fisted tyrant, fair handed dealer? What would you do as supreme (input leader title here) of the world?
As for me i would put the following rules/laws into play within days of winning world war 3 or whatever
1: Equal rights for everyone, period, except the leaders of the nations that opposed me, they become my personal bathroom scrubbers.
2: Anyone who is obviously really stupid will be either banished to the mines or if they refuse executed
3: If senior citizens stop serving a truthful purpose in life after 70 years of age they will be peacefully put down
4: Rapists, murderers and anything equally evil will be punished by death within a day of being found guilty
5: Fox news will be shut down and its building burnt and its employees sent to work at a subway
6: If anyone blames the worlds problems on video games again they will be thrown into a ring of honor with a hungry tiger
7: A code of honor will be taught in school, similarly any punks or wanna be gangstas will be sent to re-education facilites
8: All fast food except pinera bread and subway will be shut down
9: Schools will teach both evolution AND various religious ideals so the kids can make their own choices
10: Osama bin-laden will be found, and then thrown into space, because...well, im king of the world
11: Justin beiber will be asked nicely to stop making music, if he refuses i will have him executed in front of his fans
12: Same thing as justin goes for all other things that spawn annoying fans (twilight included)
And the list goes on, how about you though? what would you do with this power? I'd be interested to see what you all say

(This is supposed to be a fun little question, dont turn it into a flame war)
