Cracks and reforms
in addition to echoing ‘The Star Spangled Banner’, Eliot stresses that the way things break and reassemble, break and reassemble over and over will destroy them. Compare the way concrete expands in the heat and then contracts in the cold, so that it eventually shatters apart.
There may also be a political sense at play in ‘reforms’.
