What is the importance of lines two through four in the poem, Curse?

These lines identify the subject of the poem, as indicated by the reference to “one hundred and ten / floors” collapsing. Each tower of the World Trade Center had 110 floors that burned and collapsed on September 11. Here, the speaker’s desire is that those responsible for the attack should have to experience in slow motion the same horror of being trapped in a crumbling skyscraper. The hope that it occurs slowly implies the speaker’s yearning for the attackers to suffer as long as possible. He wants them to hear the floors falling evenly, one on top of the other, above their heads until finally all the floors “descend upon you.”
