I would make sure as soon as possible that no-one would be capable of having the authority of the whole world. Power corrupts and absolute power corrupts absolutely or as a story goes - "ring has only one master" ;) So it it is better that power is dispersed and shared between many individuals and centers of power;)

i'd find somebody else to do it

Aslam-u-alekum well if i'll get power i'll use it for a chance to serve others. i think the one having power is not the Master but a master with alot of responsibilities to run a whole system. first of all i will try to destroy the things that are destroying our lives as weapons etc. then will see how people are living.......their feelings, their pains, their sufferings all..... will try to hear unheared things........... that should be the first step of a master being a Humanbeing and also as Allah order in ever message sent by him....... " I wander thro' each charter'd street.  Near where the charter'd Thames does flow  And mark in every face I meet  Marks of weakness, marks of woe.  In every cry of every Man,  In every Infants cry of fear,  In every voice: in every ban,  The mind-forg'd manacles I hear  How the Chimney-sweepers cry  Every blackning Church appalls,  And the hapless Soldiers sigh  Runs in blood down Palace walls  But most thro' midnight streets I hear  How the youthful Harlots curse  Blasts the new-born Infants tear  And blights with plagues the Marriage hearse." Ma'slama

Hi, I would gather all the experts from around the world in order to make the best decisions as to how to distribute the wealth of nations more evenly.

i will take from the rich countries to develop and help poor one , then i will change the educational systems and mass media contents to respect morals more.
