Tell Me Why

Why is the world at war with one another? Billions spent on defences,nuclear arms, put at the fore front,when starving millions scrape. Terrorists hell bent on masacres. Hatred for each other, I cannot decipher. Because of religion? wealth? or just egotistical power? It seems as though war, which brings these days personal propaganda, be headings etc.. is to the limits. On a smaller scale the wars on the streets,gangs seeking territory. For this a respect and cash gain,heading for jail or to the morgue. World peace can never be had, as much as I`d like nothing more. Knowing my children, grand children and so forth gauranteed a safe pass.
