The short phrase "is the world insane?" is the thought that underscores the entire song, "Where is the Love?" by a group called The Black Eyed Peas. In the context of the poem, the phrase is asking the rhetorical, but powerful, question of how our world became so hostile. The answer to this question is war, greed, selfishness, and terrorism. The phrase "is the world insane?" is used in the beginning of the poem. I enjoy the balance between deepness and simplicity that this line conveys.
