Will there be peace in world?

Nope, there could never be peace. Humanity has always been a violent and warlike species, in fact i could say that war is the very nature of humanity, and it is what makes us human. Another reason why Peace is impossible is by looking through our history, throughout 200,000 years of our existence there was only 250 years of actual peace. I consider people to believe in world peace to be either naive or ignorant, Humanity would forever discriminate the different and cast war and violence among one another.
