Ask any person , what do you really want for this world when you look deep within yourself . isn't world peace not the only correct answer ? a answer everyone will give you ?
A one world government will not bring peace it bring's tyranny and suppression to sustain it's self .
Only anarchy might have a chance at world peace , depends on the people's choices . Can we live by one rule ?, do not do to others what you won't like to have done to you by others .
Seems pretty simply. One rule to live by. Don’t be a dick.
