<h3>What is a poem?</h3>
A poem is a piece of poetic writing, that is with an intensity or depth of expression or inspiration greater than is usual in prose.
Rukeyser repeated the first and last lines of the poem in order to emphasize the idea that war is violent and it destroys. War is never a thing of joy an individual should experience. It displace families, destroy properties and businesses.
