is world peace an unrealistic concept?

I dont know.......But,i would love it,if it's real of possible........I always want peace....But,i dont think its possible with all these selfish people,politics,greed etc........afterall we r humans...we'll fight anyhow...lol

It's in our nature to fight, so it's a bit unrealistic.

i dont think its a unrealistic concept unless people can out aside their differences and get along. but that will clearly never happen with all the politics, greed, etc..

Yes, I believe it is. It's only human nature to fight.
