Genocide

what does it take to kill an entire race/genocide?

a big cruel army with lots of cash?
No, Hitler had that and even he couldn't do it.

does it take a virus/germ/pathogen/a really horrible movie?
don't think so because many people have evaluated the situations that can happen (24, Forsyth's Icon) and in the end a hero saves the world.
but what if there is no hero or heroin to save the world? will the world be doomed?
even Bond or Charlie's Angels are fake. does it require a considerable amount of courage and power to be a hero or even a superhero (the latter requires extraordinary powers and logically that doesn't happen so I would cross out that possibility)?
what if a beggar saves the world by accidentally killing the virus/ germ/ pathogen/really extremely bad movie? will he be remembered or recognised or given due credit?
very unlikely. we rarely thank the soldiers or marines etc. etc. that risk their lives so that people like us can keep our butt safe. what difference does it make?

does killing a nation require economics?
considerable damage can be done (African nations) because a person's monetary status decides many aspects of life that are out of their control, such as occupation or food. social problems arise, AIDS cases make a hole in the roof and the people live in poverty. however, many nations still stand though supported by weak foundations. this is not enough

can internal conflict kill a nation?
not that I know of.

what is your opinion? I've almost run out of ideas...
