you have to break free of the us and them paradigm. or good guys and bad guys. there are 8,000 people that rule this world. they have people under them that do their bidding. the other 8billion of us are just useless eaters to them.  wars are fought to move chess pieces around the board. a bunch of the 8billion get killed and they get to test out some weapons to keep people (us) in line. the only thing they always have to do is divide the 8billion into groups and subgroups and make them all hate each other.
