Why war-war?

Why do we crave war-war? When it's better we jaw-jaw, Why do we bomb-bomb? When we are not dumb-dumb. Why do we crave war-war? When it's only bloods that pour-pour, Why do we fight-fight? When we can make peace-peace. When it's better we jaw-jaw, Why is it war that we saw-saw? When we can be friend-friend, Why is it that it's war that trend-trend? When it's only blood that pour-pour, Why can't war stay for the days of yore-yore? Why are we humans so sore-sore? That we desire war more-more. Why do we bomb-bomb? When we are better off calm-calm, Why do we kill-kill? That it's daily, lots of blood spill-spill. Are we dumb-dumb? Not to see that war makes cities slum-slum. We talk war even in hush-hush, While innocent blood gush-gush.
